RIP

3:45 PM PT Law enforcement sources tell TMZ ... Bruce volunteered to go to the hospital to have his blood drawn for blood alcohol testing. He was taken in a Sheriff's cruiser. We've also learned the woman who was killed in the white car was coming to a stop at a red light when Bruce hit her. We're told law enforcement has already determined Bruce was not speeding.

And we're told there was a 4th car involved in the accident. The woman in the white car hit a Prius in front of her before moving into oncoming traffic.

Bruce Jenner was involved in a horrific car accident on Pacific Coast Highway in Malibu at around noon Saturday, one person is dead, and it looks like Bruce caused the accident ... TMZ has learned.

Law enforcement sources tell us ... there were 4 vehicles involved in the crash. We're told there were 8 people involved and all sustained some sort of injury ... but one person died at the scene.

Eyewitnesses say Bruce rear ended the white car and that car went into oncoming traffic and was struck by the Hummer. You can see the impact in the pics below. The woman driving the white car died.

One law enforcement source said Bruce seems to be ok, but again, we're told the 7 survivors sustained some injuries, ranging from minor to moderate.

Jenner family sources tell TMZ Bruce was being chased by as many as 5 paparazzi at the time of the crash. Bruce told cops he wasn't drinking and passed a field sobriety test.

We're told Bruce had picked up his Polaris UTV after loaning it to a wounded veterans group.

"Modern Family" star Jesse Tyler Ferguson's husband slammed into another driver and killed him after what the victim's family calls an illegal move -- but he WON'T be prosecuted ... TMZ has learned.

Justin Mikita was driving his Audi in L.A. last November when he crossed over a double yellow line into oncoming traffic ... attempting to turn left.

23-year-old Nick Trela was riding his Honda motorcycle in the opposite direction and slammed into Mikita's car as it was turning left. Trela died from his injuries.

The L.A. City Attorney has just decided it will not prosecute Mikita for vehicular manslaughter, because authorities determined Trela was partly to blame because he was speeding.

In addition, sources connected to Mikita's legal team say there are several witnesses who say Mikita made a legal left turn through a break in the double yellow.

Although Mikita won't be prosecuted, he's being sued by Trela's family.

Mikita tells TMZ ... "This is a horrible tragedy. I want to respect the family and the process, so I am not going to discuss any details of the accident or the complaint at this time."

Bobbi Kristina's friend who is now accused of being a drug dealer is lashing out, saying he's being smeared -- that he's a savior, not a pusher.

Max Lomas claims through his lawyer ... he's a witness in the Bobbi Kristina tragedy, not a suspect. As TMZ reported, cops initially believed drugs were involved and family sources tell us police actually found drugs during the second search of her home.

But Lomas' lawyer says authorities have not pointed the finger at his client and he is fully cooperating with the investigation.

Former Power Ranger Ricardo Medina Jr. allegedly stabbed his roommate to death during a fight over Medina's girlfriend -- but it wasn't about sex ... just personal space.

TMZ broke the story ... the "Power Rangers Samurai" star was arrested for allegedly murdering his roommate, Joshua Sutter, with a sword. Medina claims Sutter burst into his bedroom during the brawl ... and that's when he stabbed him in the abdomen.

Law enforcement sources tell us the argument started because Sutter was pissed Medina's girlfriend was hanging out at their place when Medina wasn't home. The verbal spat eventually escalated into a physical fight.

Robin Williams' widow is fighting his 3 children over property the kids say is clearly theirs ... and the dispute is so bad it has ended up in court.

Susan Schneider has filed legal docs complaining someone came into the house days after Robin's death and took some of the actor's belongings. But the kids tell a very different story.

Zak, Zelda and Cody Williams claim Susan is essentially attempting a money grab by ignoring the plain language of his will and trust and trying to redefine it to benefit her.

Sources connected with the kids tell TMZ ... Susan refused to let them in the house after Robin died. We're told before Robin met Susan -- he was very clear in the trust he created ... he left his personal effects, including his Oscar for the movie "Good Will Hunting", movie memorabilia, action figures, graphic novels, theater masks and other items to his 3 children.

Susan -- who was only married to Robin for 3 years -- acknowledges she has no right to items related to his acting career, such as his suspenders from "Mork and Mindy," but she wants other items like the tux from his wedding and other "knickknacks."

Sources connected with the children say Susan can absolutely keep the items she accumulated with Robin while they were married, but they say she has gone way further. For example, they're indignant she is apparently trying to redefine the word "jewelry." We're told the kids are supposed to get all of it, but she's saying "jewelry" does not include his watch collection.

And people who were extremely close to Robin say he would be heartsick that this was not worked out between family ... privately.

Melissa Rivers has just filed a huge lawsuit against the clinic where Joan Rivers' heart stopped beating ... and Melissa's lawyer says the doctors acted like a bunch of groupies and not medical professionals.

The lawsuit -- obtained by TMZ -- claims gross medical malpractice, alleging during the 20 minutes doctors tried to bring Joan back to life, they didn't think to perform a tracheotomy, which facilitates breathing.

Melissa says, "The level of medical mismanagement, incompetency, disrespect and outrageous behavior is shocking and frankly, almost incomprehensible," adding, "Not only did my mother deserve better, every patient deserves better."

In addition to suing the clinic, Melissa has sued Joan's personal doctor, Gwen Korovin. According to the lawsuit, she should not have been permitted in the room where the procedure was being performed, yet she jumped in and announced, "I'll go first."

The suit claims another doctor took cellphone pics of Rivers before the emergency, while she was under sedation, with Korovin in the photos, saying Joan "will like to see these in the recovery area."

According to the lawsuit, Korovin left the room in the middle of the emergency and the allegation is that she left because she knew she wasn't supposed to be there in the first place and "wanted to avoid getting caught." The suit says Korovin simply abandoned Joan.

And get this. According to the suit, in the middle of the emergency, another doctor took issue with a colleague who wanted to scope the affected area, saying, "Renuka, you're such a curious cat. You always want to know what's going on." The suit says the doctor refused to authorize the scope.

Melissa's lawyer spoke to The NY Daily News, which broke the story, and quotes lawyer Jeffrey Bloom who says, "Had doctors acted as physicians for Joan Rivers instead of groupies, Joan Rivers would have been doing 'Fashion Police' last week."

Yorkville Endoscopy has been under intense scrutiny and they are set to lose their accreditation at the end of the month.

Bravo star Greg Plitt's favorite energy drink will not give you superpowers ... so says the company that makes WheyUP -- the product Plitt was plugging when he was hit by a train.

The pre-workout drink contains protein and caffeine, but Shadow Beverages and Snacks wants to stress what should be obvious -- it would never give anyone the ability to outrun a train.

Even though a bunch of empty WheyUp bottles were found near the tracks ... a company rep tells us Plitt wasn't drinking all of them -- he was crushing most of them with a hammer for the promo shoot.

Plitt was a co-owner of WheyUp, and the rep says he had full creative control when it came to his video shoots.

San Antonio Spurs star Danny Green has been given the green light to rock a special pair of sneakers dedicated to Stuart Scott for TONIGHT'S GAME ... the NBA tells TMZ Sports.

Green had approached custom shoe designer Jake Danklefs and ordered up a special pair to pay tribute to his fellow North Carolina Tar Heel ... and was only waiting tor permission from the league.

Well, we spoke with Tim Frank -- Senior V.P. of Communications for the NBA -- and asked if everything was a go for tonight and here's what Tim said:

"He is ... Danny was asked and given permission to wear them for one game. Unlike some reports you might have read, he was never told 'no.'"

It's a great night for Green -- since the Spurs vs. Bulls game will be nationally broadcast on TNT.

Bravo star and fitness instructor Greg Plitt will live on after death ... we've learned the network will air the episodes he shot shortly before his death.

Plitt -- who was hit by a train Saturday -- shot multiple episodes for "Friends to Lovers," which features 2 friends who attempt to take their relationships to the next level.

Production sources tell TMZ ... the network will air 3 to 4 episodes in which Plitt tests the waters with long-time bud Melanie Marden.

We don't know if they hook up on the show, but everyone involved knows it will be tough for Melanie because she'll have to go solo promoting the show.

We're told the episodes will hit the air in the next few weeks.

Cory Monteith's father could be cut off from the "Glee" star's estate funds ... after admitting he abandoned his son for most of his life.

In new court docs ... Joe Monteith, cops to not communicating with his son from the time he was "nine years old until his twenties" -- and to ditching on child support payments. Cory's mother says under the law... Joe's confession means he doesn't deserve a cent from the estate.

The docs reveal Cory's estate is worth $810,000 -- and his old roommate, Zachary Larson, will be in charge of paying off various debts ... such as $80K in taxes and another $15K to unnamed creditors.

Since Monteith did not have a will when he died in 2013 from a drug overdose -- the lion's share of his estate will go to his mother.

Darren Shahlavi, who appeared in popular TV shows including "Mortal Kombat: Legacy" and "Arrow," died of an apparent overdose ... TMZ has learned.

Shahlavi was found dead January 14 at his L.A. home and law enforcement sources tell us ... it appears he overdosed on prescription meds.

We're told the 42-year-old actor sadly had a history of drug and alcohol abuse.

He pursued a stunt career in Hong Kong in the '90s and eventually came to the U.S. to pursue acting.

In addition to the various shows, Shahlavi starred in the 2012 TV movie "Aladdin and the Death Lamp." He also had a classic fight scene in the cult movie "Ip Man 2."

We're told the L.A. County Coroner is conducting toxicology tests before determining the exact cause of death.

"Arrow" star Stephen Amell -- who fought Darren on the show's first episode -- called him a "great dude & a patient, thoughtful partner."

Bravo star and fitness instructor Greg Plitt did NOT die from stumbling on a railroad track Saturday ... he was fatally struck by a train after trying to outrun it ... to prove the effectiveness of an energy drink.

Law enforcement sources tell TMZ ... they have reviewed video of the accident and it shows Plitt standing on the tracks as the train barrels toward him. Shortly before the train reaches Plitt he assumes a runners stance and bolts down the track.

The video shows the train closes in on Plitt as he races at breakneck speed, but he loses the battle and the train "clips" him ... throwing him off the track to his death. It happens quickly and after getting struck he disappears from the video.

And law enforcement tells us they found multiple energy drink bottles near the track and authorities think Plitt may have been hopped up from the caffeine. We're told he was shooting a commercial for the product.

One of the investigators interviewed someone involved in Plitt's video shoot who said Plitt was trying to make the point that the energy drink makes you like Superman ... able to outrun a speeding train.

Brazilian pro surfer Ricardo Dos Santos died Tuesday -- one day after he was shot multiple times ... but the details surrounding the shooting are sketchy at best.

No one seems to be disputing the fact that Ricardo -- a 24-year-old rising star in the sport -- was shot and died as a result of his injuries.

But there seems to be conflicting reports about who fired the shots and why.

There are some reports that say Ricardo saw two men using drugs on the beach and asked them to stop -- when one of the men suddenly began to open fire.

Another report says Ricardo was doing home repairs with his grandfather when he got into it with some other men over a pipe that was being used in the project ... and the men shot him.

Tributes have been pouring in from all over the surf community -- with Kelly Slater dedicating a surf session to his late friend.

There are reports that a man was taken into custody in connection with the shooting. We're working on confirming the details.

Bravo's "Work Out" fitness star Greg Plitt was attempting to pull off a dangerous thrill seeking stunt -- just to sell sports drinks -- when he was hit and killed by a commuter train.

Law enforcement sources tell us Plitt was shooting a commercial for a new sports drink -- near the Burbank, CA Metrolink station -- when he attempted to outrun an oncoming train.

Sources close to Plitt say he had worked out near the tracks many times before -- but this shoot turned tragic when he tripped and fell on the tracks ... and couldn't recover in time to get out of the way.

As for why he was on the same track as the speeding train, our sources say Plitt was a highly driven adrenaline junkie. A promotional video for his website is especially eerie now ... since the whole thing was shot in the shadow of a rail yard.

The coroner says Greg's official cause of death is multiple blunt force trauma.

Famed music producer Kim Fowley, who died last Thursday, had a last wish ... he wanted to be abused and mutilated by fetish models.

Fowley -- who worked with The Runaways, KISS and Alice Cooper -- made plans in 2012 with the publisher of "Girls and Corpses" Magazine to feature his dead body on the cover.

According to emails Kim sent the publisher, a photog, and his then-girlfriend -- the singer/songwriter wanted a full spread featuring a group of fetish models violating his corpse.

Kim said, "Snow [his GF] and her fetish friends, could mutilate the body, providing real blood & guts and set my bones and blood on fire." He also said he'd fund the whole thing.

The publisher passed on the really gory stuff, but agreed to shoot his dead body with girls on top for the cover.

But here's the snag. Kim moved on, found a new girlfriend who he married, and she has control of the body. But they can't find her to allow them to shoot the body.

And when it comes to corpses, even a good composer decomposes over time.

5:45 PM PST: Cops say two men were filming Plitt on the tracks when the train conductor spotted him in the way. He attempted to stop and began sounding his horn -- but Plitt remained on the tracks.

Investigators seized video of the incident as evidence.

Fitness instructor Greg Plitt -- who appeared on the Bravo show "Work Out" -- died Saturday after he was struck by a train.

The 37 year-old was hit by a Metrolink train in Burbank around 4PM ... and according to KABC he was with some friends who may have been shooting video at the time.

One passenger reportedly said Plitt had a camcorder in his hands when he stumbled over the tracks.

Law enforcement tells us they believe Plitt was shooting a workout video at the time.

The incident is under investigation.

Plitt has modeled for Calvin Klein, Old Navy and Under Armour ... and images of his body were used to help create the physique of Dr. Manhattan in "The Watchmen."
