The son of former NBA coach Rick Adelman -- who was an assistant NBA coach himself -- was killed in Houston when he was struck by a vehicle while crossing the street ... TMZ Sports has learned.

Officials confirm 44-year-old R.J. Adelman was walking around downtown Houston around noon on Feb. 2 when he was hit by an 80-year-old woman driving a Chrysler Town & Country minivan.

According to the police report, Adelman was not using a crosswalk at the time of the accident.

Adelman was transported to the hospital in serious condition and was pronounced dead 4 hours later. According to the Harris County medical examiner, Adelman died as a result of blunt force injuries.

The driver was questioned by police and released without charges. However, we're told the accident is still under investigation.

R.J. was a scout for the Sonics and the Kings before becoming an assistant coach with the Houston Rockets while his father was the head coach. He later followed his dad to Minnesota where he took a job as Director of Player Personnel for the Timberwolves.

Former 3 Doors Down guitarist Matt Roberts died at the hands of a physician who was negligent and a pharmacy that enabled the doctor ... so claims Matt's estate in a new lawsuit.

The estate named Dr. Richard Snellgrove and Rite Aid as the ones responsible for Matt's death ... this according to new legal docs obtained by TMZ.

The estate claims Snellgrove's the one who prescribed high levels of opioids and benzodiazepines to Matt for years prior to his death. The suit claims Snellgrove has already been indicted in Alabama for Matt's death. The estate also faults Rite Aid for failing to comply with the Controlled Substances Act.

TMZ broke the story ... Matt died of an apparent overdose. He was scheduled to perform at a charity event when he was found dead in his hotel room. Matt's dad believed the possible OD was accidental.

John Mahoney's death was caused by multiple health complications, which included brain disease and lung cancer.

Our sources say the "Frasier" star's official causes of death include brain disease, lung cancer and seizures. We're told Mahoney also suffered from kidney disease and diabetes.

We broke the story ... Mahoney died Sunday in Chicago while in hospice care.

Our sources say Mahoney was cremated.

Mahoney played Kelsey Grammer's cranky father, Martin Crane, for 11 seasons on the hit sitcom. Shortly after John's death, Grammer posted, "He was my father. I loved him."

He most recently had a recurring role starring on the TV show "Hot in Cleveland," which ended in 2014. He's also had appearances on movies like 'American President,' "Say Anything..." and "Eight Men Out" over the course of more than 30 years in the industry.

John was 77. RIP

Actor Mickey Jones -- a regular on "Justified" and "Home Improvement," and a character actor in tons of huge movies -- has died ... TMZ has learned.

Sources close to the situation tell TMZ ... Mickey died at 2:17 AM Wednesday following a long illness. We're told the actor had been in and out of the hospital for the last few months. It's unclear what illness he was battling.

Mickey's been a hard working actor in Hollywood for over 3 decades. He's "that" guy ... whose face you've seen in 'MASH,' "Entourage" and "Bones." He also appeared in movies like "Total Recall," "Sling Blade," "Tin Cup" and many, many more.

He was also an accomplished drummer ... who used to play with Kenny Rogers. Mickey was 76.

The man who allegedly killed ex-Colts LB Edwin Jackson and his Uber driver while wasted drunk has been charged with 4 felonies ... and now faces more than a decade in prison.

37-year-old Manuel Orrego-Savala -- who was living in the U.S. illegally -- appeared in court today where he was charged with 2 counts of leaving the scene of a fatal accident and 2 counts of drunk driving resulting in death.

The first 2 charges are Level 3 felonies and carry 3 to 16 years in prison. The next 2 charges are Level 4 felonies and carry 2 to 12.

On top of that, Orrego-Savala has also been hit with a federal charge for illegally reentering the country after being deported. That charge carries a sentence of up to 10 years in prison.

As we've previously reported, officials say Orrego-Savala is from Guatemala and illegally entered the country multiple times over the years. He was deported twice before.

He's come under fire by Donald Trump, who on Tuesday tweeted -- "So disgraceful that a person illegally in our country killed Colts linebacker Edwin Jackson."

Cops say Jackson and his Uber driver were standing outside their car on the shoulder of a highway in Indiana when they were struck by Orrego-Savala's truck.

The car crash that killed beloved ex-NBA player Rasual Butler and his wife, Leah LaBelle, was so loud, the audio was picked up on a home surveillance camera about a block and a half away from the incident.

You can hear the tires screeching for roughly 2 seconds -- followed by a series of loud bangs.

Cops say Butler's Range Rover was traveling at very high speed around 2:30 AM on Jan. 31 when he lost control and struck several parking meters, slammed into a wall and flipped two times before coming to a stop.

Judging from the audio, it sounds like Butler slammed on the brakes and tried to avoid the collision -- but he was going too fast to regain control of the vehicle.

Butler was one of the most well-liked guys in the NBA -- and tons of huge stars like Ray Allen and Kobe Bryant paid tribute to him after the incident.

Butler was 38. Leah was 31.

Donald Trump was wrong to use Edwin Jackson's death to push his political agenda ... so says one of Jackson's closest friends, who says POTUS needs to focus on the REAL issue -- drunk driving.

We spoke with Minnesota Vikings LB Antwione Williams -- who was Jackson's college roommate at Georgia Southern. The two have been good friends for years.

Williams says it made him "sick" to see Trump using Jackson's death as a rallying cry for his immigration policy ... since the guy who allegedly killed Jackson was living in the U.S. illegally.

Instead, Williams says Trump needs to focus on the drunk driving problem in America -- since the suspect was allegedly nearly three times the legal limit when he struck and killed Jackson.

Williams also tells TMZ Sports about the kind of person Jackson was like off the field ... and shares his favorite memories from when they lived together.

DJ Khaled's fiancee's murdered brother wasn't involved in a drug deal gone bad and was simply caught in the wrong place at the wrong time when he was shot ... so says a source close to the family.

Nicole Tuck's brother Jonathan was killed in a Bronx apartment Sunday during what the NYPD called a botched weed deal. However, sources close to the family tell us Jonathan was only at the apartment to watch the Super Bowl.

Our sources say while Jonathan was there, there was an attempted robbery and, in trying to defend himself, Jonathan was shot in the back of the head -- not in the face -- as was first reported.

Jonathan was a devoted father to his 2-year-old daughter Gianna. We're told he was a stay-at-home dad who always put family first ... he was a loyal son and uncle as well. Jonathan and Nicole were very close.

DJ Khaled's fiancee's brother was murdered after an alleged drug deal gone bad ... TMZ has learned.

Cops say Nicole Tuck's younger brother, Jonathan, was shot in the face after he allegedly showed up at a Bronx apartment Sunday to buy weed. We're told the apartment was less than a mile from Tuck's home ... he allegedly got into an argument there and was shot. He was taken to a hospital where he died.

Law enforcement sources tell us a 34-year-old man was taken in for questioning about the incident.

Khaled and Nicole had a son, Asahd, in 2016.

Donald Trump says it's "disgraceful" that a former Indianapolis Colts linebacker Edwin Jackson was killed by a man who was in the United States illegally ... and is calling for democrats to get tough on the border.

As we previously reported, 26-year-old Jackson was hit by a pickup truck early Sunday morning while he was standing on the shoulder of a highway in Indiana.

Officials believe the man driving the truck is 37-year-old Manuel Orrego-Savala -- a Guatemalan citizen who had been living in the U.S. illegally. Officials believe Orrego-Savala was drunk at the time of the crash and tried to flee the scene.

Once apprehended, officials say Orrego-Savala had been previously deported twice before -- once in 2007 and again in 2009 -- yet somehow made it back and had been living in Indiana.

Now, Trump is weighing in ... saying, "So disgraceful that a person illegally in our country killed @Colts linebacker Edwin Jackson."

"This is just one of many such preventable tragedies. We must get the Dems to get tough on the Border, and with illegal immigration, FAST!"

"My prayers and best wishes are with the family of Edwin Jackson, a wonderful young man whose life was so senselessly taken. @Colts."

Jordin Sparks buried her 16-year-old stepsister ... just one week after asking for prayers following complications from an illness.

The former "American Idol" winner posted this pic Monday showing her at her stepsister Bryanna Jackson-Frias' funeral ... who died last week from sickle cell anemia. The disease causes red blood cells to stick to vessel walls, which block blood flow.

John Mahoney, the beloved dad on "Frasier," has died in Chicago ... TMZ has learned.

According to John's publicist ... he passed away Sunday in hospice care.

John most recently had a recurring role in "Hot in Cleveland." Besides his TV success, John was in tons of movies -- like 'American President,' "Say Anything..." and "Eight Men Out" -- during more than 30 years in show biz.

He won a SAG Award in 2000 for "Frasier" -- and was nominated for 2 Emmys and 2 Golden Globes. John was also active in theater, and won a Tony in 1986.

4:20 PM PST -- Oxygen sent over this statement:

“We were disappointed to learn of the complaint and its inaccurate depiction of how the series was produced, and we want to reiterate our deep compassion and sympathy for all members of the Holloway family. The documentary series was developed by a production company in close collaboration with Dave Holloway and his long-time private investigator. The show followed his continued search to find answers about his daughter Natalee from a lead he had received. We had hoped, along with Mr. Holloway, that the information was going to provide closure.”

Natalee Holloway's mom is suing Oxygen Media, claiming they duped her into providing a sample of her DNA under the false claim they had discovered what they believed were her daughter's remains.

Elizabeth Ann Holloway says in the lawsuit, Oxygen set out to do a 6-part docuseries on Natalee's 2005 disappearance. The premise was that the network had new evidence concerning her disappearance. Elizabeth says she was told they found human female remains that could be her daughter's.

Elizabeth says Oxygen lied to her ... no such remains were ever found. She says she was horribly embarrassed and never would have provided her DNA or participated in the show had she known the truth.

Justin Timberlake followed through on his plan to honor Prince during his Super Bowl halftime show ... projecting a video of the late singer instead of a full-blown hologram.

JT paid tribute to Prince about halfway through the show with a partial cover of "I Would Die 4 U" -- during which Justin was on piano, and Prince's image appeared on a giant flowing sheet behind him.

As we reported ... Justin was expected to use a straight up hologram during the performance. We were later told it would simply be a video projection of Prince rather than a hologram ... and it looks like they stuck to that.

Prince's ex, Sheila E., and his brother, Omarr Baker, both objected to a Prince hologram and assured fans this weekend that one would not appear.

1:12 PM PT -- Kim just announced that her missing brother, Christopher Cattrall, has died. She called his death "unexpected" but didn't elaborate beyond that.

Kim Cattrall is begging for help in locating her brother, who went missing Tuesday.

Kim posted a desperate plea on social media for anyone having information about Christopher Cattrall, who disappeared from his home in Alberta, Canada.

The circumstances sound suspicious. 55-year-old Christopher had 7 beloved dogs at home, and she says he would never leave them in an unlocked house. His keys, cellphone and wallet were also left in his home.

Colts linebacker Edwin Jackson was killed this weekend after being hit by a suspected drunk driver.

According to Indiana State Police, Jackson and another man, Jeffrey Monroe, were struck early Sunday morning by a driver off of I-70 in Indianapolis. Both men were killed.

Cops say Jackson and Monroe were standing near a stopped vehicle on the shoulder of the highway when a black Ford F-150 truck swerved into their area and hit them.

Police say they believe the driver of the truck, Alex Cabrera Gonsales, was intoxicated. He reportedly tried fleeing the scene on foot after the crash, but he was apprehended by authorities.

The Colts released a statement on Jackson's death, saying, in part ... "We were heartbroken to hear the news of Edwin Jackson’s passing. Edwin was loved by all in the Colts organization." A rep for the team added ... "We are shocked and saddened by this tragedy, and our thoughts and prayers are with the families of both men during this difficult time."

Jackson was only 26 years old. RIP
