Gabby Petito's cause of death is about to be revealed after weeks of waiting on a coroner's findings -- and TMZ is streaming the highly anticipated results live.

The autopsy report is being discussed Tuesday during a press conference and comes several weeks after investigators found her remains at Grand Teton National Park in Wyoming last month.

As you know by now, the coroner ruled her death a homicide.

Now, the last pieces of the puzzle in this tragedy are finally coming together -- and may very well back up what her family suspected all along ... that she was brutalized, and left out in the wilderness to perish.

Of course, the one answer that remains elusive ... who's responsible, and obviously why? The prime person of interest is Gabby's fiance, Brian Laundrie, who has gone missing and for whom a manhunt has been launched.

Laundrie remains unaccounted for, despite a handful of alleged sightings in different parts of the country.

There was a suspected sighting nearly 500 miles away from where he was living in North Port, FL -- with a man claiming to have spotted somebody on his deer cam who looked like Brian -- but cops have said they have no reason to believe, for now, Brian's in the area.

Most recently a hiker claimed to have seen Brian on the Appalachian Trail ... but nothing concrete there either. Dog the Bounty Hunter also joined the nationwide manhunt.

As we reported ... Dog's hitting the pause button on his search -- this after injuring himself on the job.

As for Laundrie's family ... they say he went hiking sometime in mid-September, but never returned. This follows an already incredibly suspicious return back to Florida without any trace of Gabby. Her family's blasted Brian and his family for clamming up on providing answers.

The feds issued an arrest warrant for Laundrie but NOT for Gabby's death -- it was for Use of Unauthorized Access Devices. Prosecutors claimed Laundrie used a Capital One Bank debit card from August 30 to Sept. 1 to purchase stuff totaling at least $1,000.

The feds haven't said it was Gabby's card, but that doesn't seem like much of a leap.

Just a few days later ... the FBI visited the Laundrie residence to retrieve some personal items in hopes they might have his DNA on them.

One thing we do know about Gabby and Brian's recent past is that they had a confrontation in Utah ... something that was briefly investigated by a police officer, who recorded one of the final images of her alive, and crying.

And, a witness called 911 shortly before Gabby's disappearance, telling the dispatcher he saw Brian slap and hit Gabby during an argument.

Now, we're going to learn what happened to her after that ... once and for all.

Gabby Petito's family is speaking out about her death and the ongoing manhunt for her fiancé, Brian Laundrie ... and they want Brian to turn himself in to law enforcement.

The Petito family and their attorney held a press conference Tuesday in New York, announcing a foundation in her name and calling on Brian to emerge from wherever he is and give himself up.

As we reported ... Dog the Bounty Hunter is hot on Laundrie's trail, alerting cops to a Florida campsite possibly linked to Brian and his parents.

The Petito family are welcoming Dog's help, and asking everyone to help find Brian just like folks helped find Gabby's body.

Laundrie's been missing for weeks and he's officially a wanted man after the feds issued an arrest warrant last week and charged him with unauthorized use of a credit card right around the time Gabby went missing.

There have been a few potential Brian sightings, like the trail cam footage in Florida and doppelganger sighting in Canada ... but so far nothing concrete.

The Petito family isn't expecting any help from the Laundrie family in locating Brian ... saying the Laundries didn't help them find Gabby.

As you know ... Gabby was found dead in Wyoming's Grand Teton National Park earlier this month. Her family held a candlelight vigil this past weekend and also laid her to rest with an emotional funeral service.

Jeff Bezos is putting his money and his ass, quite literally, on the line for his Blue Origin aerospace company's first crewed mission into space at 6 AM PT ... and TMZ will be live streaming.

The richest man in the world and 3 others are hopping into the autonomous New Shepard capsule for the highly-anticipated journey into sub-orbital space. His fellow astronauts-to-be are Jeff's brother, Mark Bezos, test pilot Wally Funk and recent HS grad Oliver Daemen.

The entire thing -- from takeoff to landing -- is expected to last around 11 minutes. The capsule will take off from a remote area near Van Horn, Texas ... about 2 hours southeast of El Paso. It'll land in the Texas desert, after being slowed by parachutes.

When they reach the edge of space -- an altitude of around 65 miles -- Bezos & Co. will experience several minutes of weightlessness. For comparison ... Richard Branson's V.S.S. Unity only got up to about 53 miles. FYI, the FAA and Air Force recognize space at an altitude of 50 miles.

While Branson went up first -- winning the so-called billionaire space race -- Bezos' flight will make history in several other ways.

If successful, Jeff's space voyage will be the first to be unpiloted with a civilian crew. Wally and Oliver would also set records as the oldest and youngest to reach space at 82 and 18, respectively.

Wally, BTW, was one of the original Mercury 13 women who took part in training back in the 1960s to show women could meet NASA's standards to become astronauts.

The launch comes 9 days after Branson's successful launch and perfect landing in New Mexico.

Richard Branson is pulling out the big guns for his first trip to space ... as in Stephen Colbert, who's hosting the live stream of Virgin Galactic's first space flight with its boss onboard.

Branson's company is launching its SpaceShipTwo -- dubbed the V.S.S. Unity -- into sub-orbital space Sunday morning from Spaceport America, New Mexico ... and we'll be streaming it here. The launch is set for 7:30 AM PT.

If all goes as planned, the British tycoon will become the first billionaire in space ... just edging out Amazon founder Jeff Bezos, who's scheduled to make a similar flight on July 20, aboard his Blue Origin spacecraft.

The launch should be pretty spectacular. Unity will get a boost of sorts ... it will be attached to a specially designed airplane that takes off traditionally from a runway, and carries Unity about 9 miles up. At that point, Unity will separate from the plane and fire rocket engines to reach an altitude of 55 miles!

David Mackay and Michael Masucci will pilot Unity through the mission, while Branson and 3 other Virgin Galactic employees evaluate the weightless experience ... which is expected to last only about 5 minutes. After that, the ship returns to Earth, much like NASA's space shuttles -- gliding to a runway landing.

The whole mission's expected to take about 2 and a half hours.

Branson founded Virgin Galactic in 2004 with the intent of leading so-called space tourism. The idea is to start taking paying passengers up to experience zero gravity while getting to see Earth from the edge of space.

In addition to Colbert hosting, Branson lined up Khalid to perform once the crew lands safely. Grab your coffee and a muffin ... the show launch should be pretty amazing.

Derek Chauvin just got sentenced for the murder of George Floyd ... with the judge giving him 22 1/2 years in prison.

The former Minneapolis police officer learned his fate Friday in Hennepin County court, where the judge in his murder trial handed down the sentence ... some 2 months after a jury found Chauvin guilty on all 3 counts, including 2nd-degree murder.

Chauvin is getting credit for the 199 days he's already served ... and the 270-month sentence is short of the 360-month sentence prosecutors wanted but, as the judge notes, is 10 years longer than the presumptive 150-month sentence.

Judge Peter Cahill found Chauvin abused his position of trust and treated Floyd with particular cruelty ... but the court said while children were present during Chauvin's fatal interaction with Floyd, it wasn't a substantial and compelling reason for a heavier sentence.

Prosecutors also argued Chauvin and a group of cops ganged up on Floyd, but the judge saw it differently and said that argument wasn't enough to justify more years behind bars.

Chauvin's defense attorney, Eric Nelson, asked for a much shorter sentence, suggesting his client get time served and probation for the manslaughter and murder convictions.

Before the judge announced the sentence, Floyd's daughter, brothers and nephew gave their victim impact statements. In a video played in court, 7-year-old Gianna said she misses her dad and she wishes she could play with him.

Chauvin was in court listening to everything, wearing a gray suit with a blue medical mask and a buzz cut, and he briefly spoke ... offering condolences to the Floyd family and suggesting some info will come out down the line that might give the Floyd family some peace of mind.

Chauvin's mother, Carolyn Pawlenty, also spoke to the court ... saying her son's replayed the fatal interaction with Floyd over and over in his head.

Floyd's family and their legal team quickly reacted to Chauvin's sentence ... expressing relief the former cop was held accountable and saying it brings the nation one step closer to healing.

DMX's Celebration of Life featured was an emotional event that featured his children, celeb friends, Kanye's Sunday Service Choir and a stern message from Swizz Beats to the people who failed X when he was still alive.

One of the more powerful moments of the entire ceremony came from X's friend Swizz Beats. He shared love to X's family and his late friend ... but didn't hide his anger in seeing some faces in the crowd he knew didn't have X's back when the rapper was alive.

In fact, Swizz says if anything, X's death has taught him the importance of loyalty and keeping good people in his circle.

We're told Kanye and the Yeezy creative team were behind the stage design for the memorial, and Kanye teamed up with Balenciaga to create DMX merch ... with proceeds going to his family.

X's red casket was center stage most of the ceremony and was first accompanied by his widowed fiancee Diseree and their son, Exodus. His other children eventually joined them on stage, and his final wishes of loving Jesus and family were relayed.

Some of X's children even got on the mic and spoke as well ... delivering somber remembrances of their father. One of his younger sons read a eulogy from his phone, fighting back tears ... and his daughter shared an original piece as well.

Nas took the mic at one point as well, with remarks that were brief but impactful -- with him remembering X's rise to fame and how he knew he'd become a musical icon. Nas and X starred in a movie together -- the cult classic 'Belly' from 1998.

There were other notable speakers, including some of the original Ruff Ryders ... Eve, Jadakiss, Styles P,  and Drag-On were just a few to take the mic as well. All of them thanked X for putting them on and paving the way in the biz.

DMX's family is also planning a more private funeral service Sunday, at a church in the NYC area.

President Joe Biden and Vice President Kamala Harris just reacted to the guilty verdict that was handed down in the Derek Chauvin murder trial ... and they say it's a catalyst for ending systemic racism.

Biden says he told George Floyd's daughter, Gianna, her father "changed the world" ... and he's calling on Americans to unite behind the guilty verdict and help make the country a better place where folks don't have reason to fear law enforcement.

POTUS says Floyd's murder in broad daylight ripped the blinders off and allowed the world to see the systemic racism rooted in America ... and Biden says the verdict is a step towards changing the country's trajectory.

Harris says the guilty verdict offers a bit of relief, but it can't bring back Floyd or take away his family's pain ... and she says now's the time to reform policing in America.

In the courthouse hallway moments after the verdict, Biden called the Floyd family and expressed his feelings that justice was served.

As you know by now, a Minneapolis jury just found Chauvin guilty of second-degree murder and third-degree murder for killing Floyd during his arrest on May 25, 2020. Chauvin was also found guilty of second-degree manslaughter.

Earlier on Tuesday, the Prez commented that he had checked in on Floyd's family and told them he was "praying the verdict is the right verdict." He also called the Chauvin case "overwhelming."

The Chauvin verdict does not mean the overwhelming nature of the case is over ... as the 3 other officers involved in Floyd's arrest are due to stand trial soon as well.

George Floyd's family is feeling joy, relief and gratitude in the wake of Derek Chauvin being found guilty of murder, but they also understand the impact of this moment is greater than them ... and say it's a reminder to keep fighting for justice.

George's brother, Philonise Floyd was in the courtroom Tuesday when the ex-cop was found guilty of 2nd-degree murder, 3rd-degree murder and 2nd-degree manslaughter ... and says he had faith a guilty verdict would come through.

Philonise says he feels relieved today, but reminded everyone this has been a long journey that didn't start with the video of his brother's murder, but way back with the 1955 slaying of Emmett Till.

He adds that this sort of injustice continues with the killing of Daunte Wright as a recent example -- and it's a reminder to keep fighting -- but says at least for today, "We can breathe again."

George's other brothers, Terrence and Rodney, also spoke ... with Terrence calling the verdict a "monumental" moment in history. Terrence and Rodney both called it a victory for humanity and thanked all of the protesters and advocates who fought and marched for justice.

As you know ... George was killed on May 25, 2020, when Minneapolis police officers attempted to arrest him for allegedly passing a counterfeit $20 bill -- and Chauvin pressed his knee on George's neck for more than 9 minutes, and George pled for his mother.

Chauvin was arrested and charged with killing George less than a week later ... and the video of the fatal incident sparked nationwide protests and riots.

Chauvin's sentencing will happen in 8 weeks, with the maximum penalty for 2nd-degree unintentional murder being 40 years in prison. Chauvin's bail has already been revoked and he's been remanded into custody.

Prince Philip, the Duke of Edinburgh and late husband of Queen Elizabeth II, is being laid to rest in an emotional farewell, with clear signs of Royal Family tension.

The ceremony was held against the backdrop of a bright and early Saturday morning across the pond at Windsor Castle ... where Philip's life, service and loyalty to the Queen is being celebrated. As expected, Harry and William were separated as they walked into the church.

QE2's husband of 73 years has been lying in repose at the castle's private chapel -- and today his coffin will be transported to St. George’s Chapel, where he'll be laid to rest in the Royal Vault.

The coffin was flanked by 9 members of the Royal family, including his grandsons Prince William and Prince Harry.

Of course, all eyes were on Harry to see how he interacted with his brother, his father, Prince Charles, and others because this is their first public interaction since Harry and Meghan Markle's Oprah interview ... where they accused members of the Royal family of racism.

After the ceremony, the brothers were spotted chatting and walking around the grounds of Windsor Castle.

While Harry flew in from California for the ceremony, Meghan did not get medical clearance to travel as she's pregnant with their second child.

As for Prince Philip, his coffin will be loaded into the back of a Land Rover he himself customized into a hearse, and the procession will pass by roads lined with military personnel saluting his naval service.

Asian hate crime is not peculiar to the United States. An Asian man was brutally attacked in London during a live stream, but he got a big assist from some enraged bystanders.

You see the perp kicking the man as the person live streaming, who goes by the name Sherwin, comes to his aid. The perp doesn't flee immediately but, as the victim repeatedly begs to "Call the police," he realizes what's up and flees.

The Asian man is bleeding from the head. It's unclear if he required medical attention. It's also unclear if the police came and hunted down the hater.

As you know, Asian hate crimes have exploded in the U.S. over the last year, thanks in part to Trump's dog-whistling over the coronavirus and the racist nickname he bestowed on it.

Joe Biden ended his first night in the White House soaking in a fireworks show over D.C. ... with Katy Perry putting a bow on a historic day.

The new President and First Lady Jill Biden wore masks and hugged on a balcony outside their new digs, watching fireworks over the Washington Monument as Katy sang her hit, "Firework."

The "Celebrating America" inauguration concert saved the best for last ... with Katy bringing down the house.

Tom Hanks hosted the 90-minute primetime concert live from D.C., braving a cold winter's night at the Lincoln Memorial.

Former Presidents Bill Clinton, George W. Bush and Barack Obama delivered a special message too ... sending Biden words of encouragement and wishing him success for the good of the country, while taking some subtle shots at the guy Biden's replacing.

Demi Lovato, Justin Timberlake, Bruce Springsteen, Jon Bon Jovi, Foo Fighters and John Legend performed virtually before Katy's grand finale ... as did Ant Clemons, Tim McGraw and Florida Georgia Line's Tyler Hubbard.

Kerry Washington and Eva Longoria were also part of the action ... introducing the acts and sharing stories about young folks making differences in their communities.

Miya Ponsetto is the symbol of white privilege, and her falsely accusing 14-year-old Keyon Harrold Jr. of stealing her phone is a modern-day reflection of what happened to Emmett Till … according to the Black teenager's mother.

Kat Harrold sounded off on Ponsetto for her actions during and since the December 26 incident at the Arlo Hotel in NYC, specifically, Miya’s denial of racism being a factor … and using her ethnicity and her age as an apparent shield for being held accountable.

According to Kat ... Miya being Puerto Rican doesn’t mean she's not racist, and being 22 years old doesn’t mean she’s too young to be excused for it. She points out that Emmett Till was killed as a result of false allegations made by a white woman who was 21 … and Kat believes that racial injustice is reflected in her son’s case.

Kat says the proof is in how the hotel reacted to the situation when Miya accused her son of stealing her phone. She claims the Arlo defaulted to questioning the Black teenager but did NOT question Miya. Kat says the hotel immediately sided with her instead and calls this a clear example of white privilege.

As for the Arlo … attorney Ben Crump and Keyon’s parents are calling for a ban until the hotel condemns the individual racism allegedly shown by Ponsetto, and takes responsibility for the racial profiling they believe it demonstrated.

They lay a lot of the blame on the hotel manager for not de-escalating the situation, and accuse him of treating the Black teen like he was guilty from the jump … forcing him to prove he did nothing wrong. Even worse, they point out that Miya was not even a patron of the hotel … yet she was treated with more respect than Keyon and his father, Keyon Sr. -- who were actually staying there.

Their rallying cry -- "No more, Arlo!"

As we've reported ... Ponsetto was arrested last week in SoCal, flown back to NYC where she was charged with attempted assault, attempted robbery, grand larceny and endangering the welfare of a child for her altercation with the teenager.

However, Miya was NOT charged with a hate crime, and the prosecutor never even mentioned any racial components to the case in court Saturday. Keyon Jr.'s parents -- Keyon and Kat -- previously told us they believe the ordeal is reflective of racial injustices as a whole.

Mike Tyson and Roy Jones Jr. just ripped off their shirts and showed off their incredible physiques at the weigh-in for their big fight ... and man, these guys are ripped!

54-year-old Tyson and 51-year-old Roy both look amazing for their age -- really, for ANY age -- as they gear up to fight on Saturday night.

Tyson weighed in at 220.4 pounds. Jones Jr. was 210.

Both men appeared calm and focused -- and told TMZ Sports they plan on spending their Friday night relaxing and watching karate movies to get in the right headspace.

Jake Paul also put on a show at the weigh-in -- dressing up like a Super Saiyan from "Dragon Ball Z" ... and warning his opponent Nate Robinson to not let his kids watch the fight, because it will scar them for years to come.

36-year-old Nate is a former NBA star and 3-time NBA Slam Dunk contest champion. He said he's fighting 23-year-old Paul to prove he's still an elite athlete.

Earlier in the day, Roy Jones Jr. told us his pre-fight meal plans -- and why he's so excited to get back in the ring.

Funny moment with Mike Tyson when he was asked about his famous quote, "Everyone has a plan until they get punched in the mouth."

So, what happens when Mike gets punched in the mouth?

"We'll go to Plan B -- I'll punch him back!"

The fight is set to go down Saturday night at Staples Center in L.A. -- the weigh-in took place at a nearby hotel.

Everyone at the weigh-in site was required to undergo COVID testing -- including our TMZ photog, who was also mask'd up and keeping his distance.

As we previously reported, both Mike and 51-year-old Roy have made it abundantly clear they will be trying to take each other out from the opening bell of their 8 round exhibition (available on PPV via cable and satellite, and PPV streaming at Triller).

The event is going to be insane -- with performances from huge stars like Lil Wayne, French Montana, YG, Wiz Khalifa and more.

Ahmaud Arbery's mother says the father and son accused of murdering her son did not give him a chance to go home ... so they shouldn't get to go home either.

Wanda Cooper-Jones spoke in a Georgia courthouse Thursday at the end of a long bond hearing for Travis McMichael and his father, Gregory McMichael, who are trying to convince the judge they should be released. They've been in jail since May when they were charged.

Ahmaud's mom says the 2 men are trying to present themselves as the good guys and her son as the criminal, while ignoring what she believes is an absolutely unjustifiable killing.

According to Cooper-Jones ... the McMichaels are just as dangerous now as they were on the day Ahmaud was killed, and it would be another injustice to let them go home while they wait for their trial.

Earlier during the hearing, a handful of character witnesses spoke on behalf of Travis and Gregory and why they believe they should be granted bond. Travis' mom and friends said he's a great father and a happy person who would pose no threat of fleeing.

Likewise, Gregory's wife and coworkers said he poses no flight risk, and his landlord said he's always been a good tenant.

The judge did not make a decision yet, but is expected to when the hearing continues Friday.

William "Roddie" Bryan, the man who authorities say recorded Ahmaud's slaying, was not involved in this hearing, but was first denied bond back in July, when a judge deemed him a flight risk.

As we've reported ... all 3 men were indicted by a grand jury back in June, and they're facing 9 felony charges ... including 4 counts felony murder, 1 count of malice murder, 2 counts aggravated assault, 1 count of false imprisonment and 1 count of criminal attempt to commit false imprisonment.

The 3 defendants last appeared in court together in July, when they all entered not guilty pleas.

Authorities say Travis fired the fatal shots during a struggle with Ahmaud on February 23 while Bryan recorded the incident. A GBI detective previously testified Bryan told police he heard Travis call Arbery a "f***ing n*****" after shooting him.

Protesters gathered in front of the courthouse Wednesday before marching and chanting "no bond."

Joe Biden and Kamala Harris both gave rousing speeches to an enormous crowd as they declared victory in the 2020 Presidential election.

Biden sprinted to the podium, then told the crowd his victory was clear and convincing. He was clearly messaging that Donald Trump's challenges will amount to nothing.

He then got presidential, telling the crowd he will restore respect for America around the world. He said he was heartened by the joy he's observed today all over the world.

Biden then laid out the work ahead, starting with subduing the COVID pandemic, restoring the economy, and on and on.

Kamala Harris introduced Biden. She came out to thunderous cheering and honking, to Mary J Blige's "Work It,"and began her speech by referencing the late John Lewis, who said ... "Democracy is not a state. It's an act." As Harris explained, there's no guarantee that democracy will endure ... it's all about action.

Harris took some oblique shots at Trump, saying voters chose hope, unity, decency, science and truth. But, most of what she did was inspirational, talking about her historic rise and her late mother's mantra that anything is possible.

Her most memorable line ... "I may be the first [female Veep] in this office. I will not be the last."
