RIP

3:45 PM PT -- An Instagram user just posted video from inside Borderline Bar & Grill during the shooting. In the video you can see a shadowy figure moving around as gunshots ring out -- the IG user claims that figure is Long, and he was firing shots at injured victims at the time.

8:52 AM PT -- According to more dispatch audio -- obtained by TMZ -- officers can be heard communicating Long suffered 3 gunshot wounds to the chest and is down. They describe him as wearing all black with a beard.

8:35 AM PT -- Long served in the U.S. Marine Corps from 2008-13 and was deployed to Afghanistan from 2010-2011, his last duty assignment was in Hawaii. His military occupational specialty was machine gunner.

He was decorated too ... some awards included the Navy Unit Commendation (x2), Navy Meritorious Unit Commendation, Combat Action Ribbon, Marine Corps Good Conduct Medal, Afghanistan Campaign Medal, Global War on Terrorism Service Medal and the National Defense Service Medal.

7:40 AM PT -- President Trump has ordered flags flown at half-staff on all public buildings and military facilities until sundown on Saturday.

6:45 AM PT -- The shooter's been identified as 28-year-old Ian David Long -- a retired Marine who served in Afghanistan.

We found this pic of Long at a cemetery that appears to be in the L.A./Thousand Oaks area. We're told he was heavily tattooed.

A horrific scene unfolded at a bar packed with college students Wednesday night as a gunman opened fire, and at least 12 people are dead.

Borderline Bar & Grill in Thousand Oaks was hosting its weekly College Country Night. College students from the area were enjoying themselves, line dancing when, at around 11:20 PM, shots rang out.

A man dressed in all black began firing a handgun. Several patrons broke windows to allow others to escape, cutting themselves on shards of glass as they exited.

Sheriff's deputies responded quickly and as they rushed the bar the gunman opened fire on them, killing Sergeant Ron Helus.

Long reportedly drove his mother's car to the bar. He threw smoke bombs into the crowd before opening fire.

No word yet on the number of injured, but around a dozen people are known to have gone to the hospital. It appears some may have driven themselves and may not be accounted for yet.

President Trump tweeted, "Great bravery shown by police ... God bless all of the victims and families of the victims. Thank you law enforcement."

We spoke with multiple coaches from Long's high school baseball team who remember him as a sad loner who didn't have many friends. As one coach put it, he had "sad eyes" and never appeared happy. We're told he also wore an army jacket to school often and it was clear he had ambitions to join the military. One coach tells us, "He was a quiet kid. Respectful. But kept to himself."

Story developing ...

11:50 AM PT -- Tamera just revealed her niece Alaina was one of the victims in the attack ... saying, "Our hearts are broken. We just learned that our Alaina was one of the victims of last night's shooting at Borderline Bar in Thousand Oaks."

She continues, "Alaina was an incredible young woman with so much life ahead of her and we are devastated that her life was cut short in this manner."

Tamera Mowry is desperately searching for her niece who was at the college bar where a gunman opened fire and brutally killed 12 people.

Tamera's niece, Alaina Housley, was one of just a handful of girls who went line dancing Wednesday night at Borderline Bar & Grill in Thousand Oaks ... this according to a tweet sent by Alaina's friend who added Alaina was the only girl unaccounted for among her friends.

Tamera responded to the tweet saying, "Ashley this is her aunt Tamera Mowry Housley. Can you please DM me your information?" The exchange is pretty heartbreaking ... Ashley replied saying she's been in contact with Alaina's uncle and so far there's nothing new to report.

Tamera's husband, Adam, went looking for Alaina at a local hospital but a reporter tweeted guards wouldn't let him in because the hospital was on lockdown. Making matters worse ... Alaina's Apple Watch and iPhone still showed her location at the bar, this according to the L.A. Times.

Adam told the newspaper, "My gut is saying she's inside the bar, dead. I'm hoping I'm wrong."

Jared Goff and his teammates are devastated by the bar shooting that left 12 people dead just miles from the team's headquarters ... with some players vowing to help in any way possible.

FYI -- the L.A. Rams practice facility in Thousand Oaks is just 5 miles from the Borderline Bar & Grill, where David Ian Long opened fire around 11:20 PM on Wednesday.

Goff spoke out about the tragedy on Thursday ... saying "Heartbroken for our community. Thinking about everyone involved as well as friends and family of the victims. Keep them in your thoughts and prayers."

Offensive lineman Andrew Whitworth added ... "I’m just sorry to those affected. I don’t have words that I feel can help. But I promise to find a way to help support our community through this tragedy!"

The team released a statement saying, "The Los Angeles Rams organization is heartbroken by the horrific shooting that took place last night in our community of Thousand Oaks."

"Our thoughts and prayers are with the victims, their families and our entire community."

Punter Johnny Hekker ... "Praying comfort and healing to those affected by this senseless shooting. Thank you to the first responders who put their lives on the line to protect and serve us every day."

"Thousand Oaks is my home; I will do everything in my power to help those in need of support."

Cooper Kupp added, "Heartbroken. Thoughts and prayers are with the people of this community, and those that have lost loved ones."

The L.A. Chargers also shared condolences ... "We are deeply saddened by the terrible news coming out of Thousand Oaks this morning."

The man who allegedly shot and killed Angela Simmons' ex-fiance has turned himself into authorities ... TMZ has learned.

The lawyer for Michael Williams tells TMZ ... Williams turned himself into the Atlanta Police Dept. just moments ago. The 44-year-old has been charged with murder.

The attorney, Jackie Patterson, tells us his client denies the allegations that he shot and killed Sutton Tennyson, Angela's ex-fiance and father of their child.

As we reported ... Sutton was shot and killed over the weekend at his home. Cops say they found him dead in his garage with multiple gunshot wounds. Cops added Sutton was talking in the driveway with another man when the conversation got heated and he was shot. The suspect fled in a car.

Following Sutton's death, Simmons said, "Thank you for leaving behind my greatest gift. I'm hurting. I'm numb. Thank you for the outpouring of love everyone. I can't believe I'm even saying Rest in Peace Sutton. I promise to hold SJ down in every way I promise."

Dennis Hof, unfortunately, won't be able to serve the people of Nevada -- 'cause he's dead and all -- so the Silver State's running good old-fashioned want ads to find a replacement ... TMZ has learned.

A Nye County spokesperson tells us officials there plan to advertise the vacancy on their site, and in local newspapers. Nye is one of 3 counties that make up Nevada's 36th district, which Dennis would've repped if he was alive. Lincoln and Clark counties are the others.

We're told potential candidates will have until the end of November to submit applications, and then members of the Board of County Commissioners in the 3 counties will get together and pick whomever they deem fit. There are some requirements, though.

The replacement for the late brothel owner -- who was posthumously elected Tuesday night -- must be Republican, and must live within the district.

While all 3 counties get a say in who ends up being picked, we're told Nye County will get slightly more votes because it has more residents. We're told board members will likely meet in the first week of December to make their official pick.

Former pro boxer Mario Oscar Melo -- who fought Michael Moorer for the WBO light heavyweight title in 1990 -- died Sunday after choking on dough during a croissant-eating contest in Argentina.

**WARNING -- THE VIDEO IS DISTURBING**

Video shows several men violently trying to dislodge the croissant from Melo's throat while on stage at the event in Buenos Aires, but to no avail. Melo was rushed to a nearby hospital but was declared dead on arrival.

Melo was 56.

Reports say Melo was on his 3rd croissant when he started to choke. The pasty is known locally as a medialuna.

While eating competitions are popular around the world, the Major League Eating organization (which oversees huge events like Nathan's Famous 4th of July hot dog contest) always requires paramedics to be on hand in case a situation like this happens.

According to local reports, there was a firefighter and a doctor in the crowd who raced up and tried to help -- but it does not appear there was a dedicated, trained medical staff at the event.

Melo was 21-9 as a pro fighter, with the Moorer fight being his most famous bout -- though he lost in the 1st round.

8:15 AM PT -- According to the report, Mac's assistant found him unresponsive on his bed in a "praying position" -- kneeling forward with his face resting on his knees. The assistant described him as already being "blue" during the 911 call.

There was a 1/4-inch abrasion on the bridge of his nose, and there was blood coming out of one nostril.

An empty bottle of alcohol was found on the nightstand, near Mac's body ... and a bottle of prescription pills was found in the bathroom. The list of pills recovered in the home include Xanax, oxycodone, hydrocodone, and generic Adderall.

Cops found a rolled-up $20 bill with white powdery residue in Mac's right pocket -- and an iPad in his home studio had "linear white powdery residue" on it. There were also 2 baggies found with the white powder.

We're told the amount of each drug was not necessarily a lethal amount, but the combination is what killed him.

As part of the report, the Coroner detailed the location of all of Mac's tattoos, and described each of them -- including his "Most Dope," Einstein face and "No Woman No Cry" ink.

Mac Miller died from a mix of fentanyl and cocaine ... TMZ has learned.

The L.A. County Coroner's Office released its toxicology findings, and according to the report Mac died from "mixed drug toxicity" -- specifically fentanyl, coke ... and alcohol too. The Coroner categorized his death as an accidental overdose.

TMZ broke the story ... Mac died back in September. He was found around noon in a bedroom at his San Fernando Valley home. He was pronounced dead at the scene.

As we reported ... a male friend called 911 from Mac's home. Emergency dispatch audio revealed first responders were called for a patient in cardiac arrest. Mac battled with substance abuse for years and it's what ultimately led to Ariana Grande breaking up with him.

He was arrested for DUI and hit-and-run back in May after wrecking his G-Wagon on a utility pole. He fled the scene but cops said he later confessed when they tracked him down at his home. He blew 2 times the legal limit. Ariana later tweeted, "Pls take care of yourself" ... clearly showing concern about his sobriety.

Julian Edelman doesn't play for Pittsburgh ... but he's got the city's back regardless -- wearing a Jewish star hat Sunday, and saying last month's synagogue shootings were "uncalled for."

After the Patriots beat the Packers last night, the WR -- who is of Jewish heritage -- wore a Team Israel hat from the World Baseball Classic.

He told reporters he wanted to show the people affected by the anti-Semitic shootings inside the Tree of Life synagogue that they're in his thoughts.

"Just letting the people out in Pittsburgh know I'm thinking about them," Edelman said ... "I'm sending vibes and they're in our prayers. It was a big hit to the community, and it's uncalled for."

"So, I just let them know, 'Hey, I'm behind you and I'm supporting.'"

The Pittsburgh Steelers -- who played in Baltimore on Sunday -- held a moment of a silence for the victims before their win over the Ravens ... while star QB Ben Roethlisberger wore "Stronger Than Hate" cleats.

Members of the team also attended funeral services last week for two brothers, Cecil and David Rosenthal, killed in the tragedy.

Ron Jeremy got right back to his usual shtick after giving a speech memorializing his late pal and Bunny Ranch owner, Dennis Hof ... signing cleavage and cheesin' with fans.

The legendary porn star gave a eulogy Saturday at the Casino Fandango in Carson City, NV, where Hof's memorial service was held, and a bunch of his friends paid tribute to the recently deceased Hof ... who was found dead at his home earlier this year.

Ron was one of the keynote speakers ... and, at one point, he entertained the crowd with a story about Dennis' HBO-produced show, 'Cathouse,' telling them how successful it was and how Dennis kinda pissed off execs with a clever slogan using their 3 letters.

Afterward, eyewitnesses tell us Ron was getting approached left and right by folks who wanted pics and autographs -- some of whom asked for it ink to skin, like this lady here.

Ron's ran into some legal issues lately with his public appearances after some people claim he's gotten way too handsy ... but this meet-and-greet looks completely consensual.

6:25 PM PT -- Tennyson's attorney, Daniel Nottes, tells TMZ ... "It's devastating to hear about this tragedy. Mr. Tennyson was a loving father and an overall prince of a man." He adds that Tennyson's child custody case with Angela regarding their 2-year-old is now over -- she will get sole custody, and it's sad his son will grow up without a father.

8:10 AM PT -- The Atlanta PD tells TMZ, they responded to a "shots fired" call at Sutton's home. Officers found him dead in his garage with multiple gunshot wounds. It now seems it was NOT a home invasion. Cops say Sutton was talking in the driveway with another man when the conversation escalated and he was shot. The suspect fled in a car.

Angela Simmons says she's hurting bad in the wake of her baby daddy's murder.

Angela is reeling from the death of ex-fiance, Sutton Tennyson, who was shot and killed Saturday at his home. It appears his death was the result of a home invasion robbery.

Angela and Sutton have a 2-year-old son, Sutton Jr., and with that she took some solace, saying, "Thank you for leaving behind my greatest gift. I'm hurting. I'm numb."

Angela went on ... "Thank you for the outpouring of love everyone. I can't believe I'm even saying Rest in Peace Sutton. I promise to hold SJ down in every way I promise."

Sutton and Angela called off their engagement in 2017.

UPDATE 8:05 PM PT -- Check out the post and hear the new song.

Ariana Grande isn't going to let Pete Davidson define their relationship and breakup on "Saturday Night Live" tonight, because TMZ has learned she's releasing a song 30 minutes before 'SNL,' and his name is right there in the lyrics.

Record label sources tell TMZ, the overarching theme of the song -- titled "Thank u, next" -- is empowerment ... what she's been through in her relationships and other experiences. We're told it is not a diss track.

Our sources say she specifically names Pete, Mac and others ... but she doesn't go after Pete the way she did earlier this week after he publicly joked about their breakup. She had accused him of being a hypocrite ... pretending he wasn't into being in the spotlight yet hanging on for dear life.

We're told Ariana felt betrayed by Pete and doesn't want to take the chance that he'll talk about their breakup tonight on 'SNL' as she just sits by. As we reported ... Pete was planning on addressing it, but 86'd the idea after she made it clear they had an agreement to keep their relationship private. Nonetheless, anything could happen.

Among the lyrics, which she posted, "Got so much love ..... got so much patience ..... I've learnt from the pain ..... and turnt out amazin ..... say I've loved and I've lost ..... but that's not what I see cause look what I got ..... look what you taught me."

It goes on ... "Cause look what I found ..... ain't no need for searching and for that I say ..... thank u, next."

The song will be released at 11 PM ET.

Chris Cornell was funneled dangerous drugs in enormous quantities by his doctor, without so much as a visit or even a phone call, and that's what caused him to commit suicide ... so claims his widow.

Vicky Cornell is suing Dr. Robert Koblin for malpractice, claiming the doctor prescribed 940 doses of the anti-anxiety drug Lorazepam (aka Ativan) as well as Oxycodone during the last 20 months of his life, without even examining the Soundgarden singer, performing lab studies ... anything to determine if Chris was in danger.

According to the lawsuit, obtained by TMZ, Chris was a known "addiction-prone individual," yet the doctor took no steps to protect him. The suit claims, in 2004, Chris' therapist for his substance abuse referred him to Dr. Koblin, so the doctor well knew Chris was an addict.

The lawsuit alleges Lorazepam increases the risk of suicide in addiction-prone individuals by impairing judgment and rational thinking. It also diminishes impulse control. TMZ broke the story, the suicide seemed to have come from out of the blue. Vicky spoke with Chris during sound check in Detroit the day he died and everything seemed fine ... yet hours later he took his life.

According to the lawsuit, Dr. Koblin never warned Chris about the dangers of suicide or other side effects of long-term Lorazepam use.

The suit claims Dr. Koblin permitted non-physician staff to write hundreds of Lorazepam prescriptions, without showing any medical necessity or providing any monitoring.

Vicky and her 2 children are suing for unspecified damages.

Mac Miller's gotta be feeling the love after his closest friends and thousands of his fans celebrated his life and his music with a concert in L.A.

The tribute show, "Mac Miller: A Celebration of Life," went off without a hitch, and was filled with some emotional moments courtesy of Chance the Rapper, Travis Scott, John Mayer, SZA, ScHoolboy Q and many more.

All the artists gathered at L.A.'s Greek Theatre either played Mac's songs or songs about him ... and the giant screen onstage was filled with photos and videos of Mac all night.

Mayer played Mac's "Small Worlds" and told the crowd he was "really nervous" doing it. Chance and several others choked up while thanking Mac for his music, friendship and opportunities in the biz. As SZA put it, "Without Mac, there would be no me. God bless you, we love you so much, Mac."

Barry Bonds says he's been crying over the death of his good friend and mentor, Willie McCovey -- but says he promises to pass along the wisdom he learned from the SF Giants legend.

Bonds and McCovey formed a very strong bond over the years -- with McCovey recently blasting the Baseball Hall of Fame voters for not inducting Barry. He called it a "sin."

So, when Bonds learned McCovey had passed away Wednesday, he was devastated.

"Mac, I am crying over losing you even when you told me not to," Bonds wrote.

"I remember asking you what I would do without all of you around. You told me when that day comes - and it will one day - to keep the tradition of Giants baseball living forever."

"You told me to help the next generation of ball players get better. You told me to be thankful that we had so much time to spend together and talk about the love we have for the game, San Francisco, the Giants and for each other."

"You wanted me to be happy that we had a love and friendship that will never disappear and will be in our hearts forever."

"Uncle Mac thank you for your mentorship and unconditional love for me and my family. You will be dearly missed."

McCovey was a beast on the field -- one of only 4 Giants players in the elite 500 Club ... along with legends like Willie Mays, Mel Ott and Barry.

McCovey was 80.

San Francisco Giants legend and Hall of Fame first baseman Willie McCovey has died.

McCovey, who played 19 seasons for the Giants and is one of the franchise's most beloved players, passed away peacefully Wednesday at Stanford Hospital after battling ongoing health issues.

Willie played for the Giants from 1959-73 and was inducted into the National Baseball Hall of Fame in 1986.

The first baseman was one baseball's most feared hitters during the 1960s and '70s, and his 521 home runs are still tied for 20th on MLB's all-time list.

Willie was a 6-time All-Star and the 1969 National League MVP. His 18 career grand slams are the most in NL history.

The Giants retired Willie's No. 44 and he has a statue outside the club's ballpark.

When the Giants started playing at AT&T Park in 2000, the area beyond right field was dubbed McCovey Cove, an homage to the many homers he belted to right field during his playing days.

Lil Xan has been burning the midnight oil to honor Mac Miller in song, and that's why he just canceled a bunch of his shows.

Sources close to the Cali MC tell us the reason Xan axed 5 upcoming shows -- mostly in Texas and the Midwest -- is to recharge after long hours in the studio recording a new album called, "Be Safe" ... a tribute album to Mac, who died in September.

We're told Xan's been working nonstop on it -- if he wasn't onstage somewhere, he was in the studio trying to perfect the project -- and, at this point, he just feels burnt out.

Instead of putting on half-ass concerts, our sources say Xan opted to rest up and then hit the ground running again in Colorado on Nov. 6. He's planning to reschedule the canceled shows, but anyone who wants a refund will get it.
