RIP

2:45 P.M. PST -- TMZ obtained a police report from Orange County, where Michael was arrested for criminal threats just 5 days before disappearing. According to the report, Cavallari showed up to his girlfriend's apartment with a loaded shotgun after a verbal dispute, and made threats. Cops also say they smelled a strong odor of alcohol on his breath. He was released 2 days later, and then disappeared.

1:23 P.M. PST -- Law enforcement tells TMZ they located remains they believe to be Michael at 10:30 A.M. They say the body was found in a steep and very rocky area.

Kristin Cavallari's brother and Bears QB Jay Cutler's brother-in-law has been found dead in Utah.

30-year-old Michael Cavallari's car was found abandoned November 27th. It appears he wasn't reported missing until 3 days ago.

In a statement to TMZ, Kristin says, "We have just been informed by the authorities my brother's body has been found. This is a very painful time and we are still processing it all."

It's unclear how Michael died, but he's struggled for many years with alcoholism and has had more than his share of trouble.

Scott Weiland's tour bus was a pharmacy on wheels ... police found a stash of drugs on board that ran the gamut from hardcore narcotics to prescriptions to ED meds.

TMZ obtained a copy of the search warrant Bloomington, MN cops got to search Weiland's bus after his death -- and it shows they found at least 2 bags of a white substance. They've already said that substance tested positive for cocaine.

Also on the bus -- a generic version of Xanax, 2 different brands of sleeping pills, Buprenorphine ... a synthetic opiate painkiller, and Viagra. There was also Ziprasidone ... which is used to treat bipolar disorder and schizophrenia. Scott was diagnosed as bipolar in 2001.

According to the docs, all of those drugs were found in a bedroom on the bus. We know Scott's body was found in a bedroom ... although the document does not mention his name.

Cops also found one bag of a green, leafy substance.

Darel Evans -- an anti-violence activist who was featured in the Sundance documentary series "Brick City" -- was shot to death late Monday night in Newark, NJ. He was 33.

So far, authorities are investigating the motive and have released no details about the incident so far. No arrests have been made and no suspects have been identified.

Evans, a former gang member who went by the name Creep, was profiled as part of the award-winning TV series.

Scott Weiland emotionally abandoned his 2 children and completely gave up on even trying to be their parent ... according to his ex-wife.

Mary Weiland wrote a scathing open letter to Rolling Stone about Scott's death. She pulled no punches, saying ... reports Scott had been drug-free for years and loved spending time with his kids were false. She says the truth is Scott "was a paranoid man who couldn't remember his own lyrics and who was only photographed with his children a handful of times in 15 years of fatherhood."

She also said she can't say he's in a better place now because, "He belongs with his children barbecuing in the backyard and waiting for a Notre Dame game to come on."

Mary added, Scott's kids -- Noah, 15 and Lucy, 13 -- "never sought perfection from their dad. They just kept hoping for a little effort."

One of Britney Spears and Ryan Gosling's former 'All New Mickey Mouse Club' co-stars was found dead in his NYC apartment ... TMZ has learned.

According to law enforcement sources Marque "Tate" Lynche's roommate found him on Sunday afternoon. He was only 34 years old. The medical examiner's office conducted an exam of the body on Monday, but hasn't determined a cause of death yet.

Lynche was a Mousketeer from 1993 to 1995 -- and shared the camera with Britney, Ryan, Justin Timberlake and Christina Aguilera. He later appeared on Season 3 of "American Idol" and made it to the semi-finals.

Tiffany Thornton's husband, former MTV star Chris Carney, was so wasted before Friday's fatal car crash ... he probably didn't think twice about getting in a car driven by a guy who was liquored up.

People at The Tavern in Little Rock tell us, Chris started off with beer and moved to the hard stuff. We're told he was slamming shots of Fireball Whiskey and doing Vegas Bombs to the point he couldn't stand up.

Chris was in no position to judge the sobriety of the driver, his friend Ezekiel, who we're told had been drinking beer and downing some shots.

As we reported, Carney and Ezekiel died early Friday after their SUV drifted off the road and struck a tree. We're told neither were wearing seat belts.

Chris struggled with alcohol over the years but his mom tells us she believed he had been sober for a year.

Scott Weiland had semi-strict rules in place to prevent him from falling off the wagon during his tour, but there was a gaping hole in the plan.

TMZ got hold of a backstage rider from Weiland's management team, which requires "sober stage hands" for his shows.

Members of the Wildabouts got a full stocked bar in their dressing rooms -- everyone except Scott. They got whiskey, vodka and beer. Here's what's curious ... the rider says Scott gets a bottle of Pinot and a bottle of organic vodka.

Scott was a hardcore addict and just about every respectable addiction expert out there says addicts should stay away from drugs and alcohol. It's weird Scott -- who fought a losing battle for much of his adult life -- was provided booze that could trigger a relapse.

Our sources say the no-drug policy was jettisoned once the band was on the road, and that explains how cocaine ended up in Scott's bedroom on the tour bus.

The apparent relapse was underscored by accounts we got from some big musicians, who say Scott was "drunk texting" them over the last few days of his life.

Tour merchandise for Scott Weiland's band that seemed really cool yesterday is now just really tragic ... yet still available for purchase.

The gear features Scott's picture with the slogan "Not Dead and Not For Sale" -- playing off the rumors that frequently swirled prematurely about the rock star's death. It was also the title of a memoir written about Scott.

Arguably, the clothing is more valuable now after Scott's death ... something fans clearly realize since there's a bunch of new listings on Ebay for shirts and sweatshirts with the phrase.

Scott's own Amazon store is still hawking the stuff too ... if you want to pay retail.

Actor Robert Loggia -- who played drug kingpin Frank Lopez in "Scarface" -- is dead.

Loggia, who was nominated for Best Supporting Actor for "Jagged Edge," died at his home at noon Friday.

Loggia's wife, Audrey, tells TMZ her husband was struggling with Alzheimer's for the last 5 years. She says things took a drastic turn for the worse Wednesday, he seemed to rebound and then died suddenly and peacefully at home.

Audrey says she and their daughter Cynthia were at Robert's bedside when he passed. The couple had 4 kids. They've been married for 33 years.

She says, "He was an awesome husband and an awesome father."

Variety first broke the news of Loggia's death.

RIP

Scott Weiland's bandmate Tommy Black has been arrested for possession of cocaine on the tour bus where Scott died.

Police say they found a small quantity of a suspected controlled substance that field tested positive as cocaine in the bedroom where Scott was found.

They also found another small amount of the same substance in an area of the bus occupied by Black ... who is a guitarist for Scott Weiland and The Wildabouts.

Black was arrested and booked for 5th degree felony possession of drugs.

Scott Weiland's former bandmates in Stone Temple Pilots crafted a letter thanking him for his talent, but also acknowledging his demons.

It begins, "Let us start by saying thank you for sharing your life with us. Together we crafted a legacy of music that has given so many people happiness and great memories."

Band members Robert DeLeo, Eric Kretz and Dean DeLeo added ... "We know amidst the good and the bad you struggled, time and time again. It’s what made you who you were. You were gifted beyond words, Scott. Part of that gift was part of your curse."

Scott Weiland's wife says her husband was clean when he died.

Jamie Weiland tells us her husband had not been doing any drugs for years ... although she admits he has been drinking socially.

Our sources say drugs were found on the bus, but Jamie insists they were not Scott's.

Jamie says there was a pact among the band not to do drugs ... at the very least that pact seems to have been broken by someone on the bus.

As we reported, several prominent musicians have told us they were alarmed over the last 4 days, saying Scott had been deep into crack cocaine ... something Jamie vehemently denies.

Jamie, who says she was touring with the group but left them a week ago, says, "He [Scott] was the best he has ever been."

Some legendary musicians were in touch with each other 4 days before Scott Weiland died ... worrying he had fallen off the wagon again, and was deep into crack cocaine.

Our music sources say Scott had NOT slipped back into heroin abuse -- something that had plagued him during much of his adult life. But we're told crack, as well as heavy drinking, were front and center in the days before he died.

One source -- a huge rock star -- got a call before TMZ broke the story ... from someone connected to Scott who said he had died at around 7:30 PM of a drug overdose. Authorities in Minnesota have not confirmed this with TMZ.

One day before his death, Scott was on SiriusXM talking about his tour ... and challenging ISIS.

Disney star Tiffany Thornton's husband Chris Carney -- a musician and TV star -- was killed in a single car accident in his home state of Arkansas.

Carney and another man, Ezekiel Blanton, were pronounced dead on the scene. They wrecked early Friday morning when their car flew off the road while going around a bend and slammed into a tree. At least one was ejected from the car, which was driven by Blanton.

35-year-old Carney was on the MTV reality show "twentyfourseven," and was the lead singer of the group Prom Kings. Chris and Tiffany -- star of "Sonny with a Chance" -- have been married since 2011. Just last year they moved back to Hot Springs, AR ... where Chris' mother is mayor.

Scott Weiland died from cardiac arrest ... this according to first responder audio.

TMZ has obtained communications between the Bloomington, Minn Police Dept. and the Hennepin County Sheriff's Dept. They had received a 911 call that Scott appeared to be dead in his tour bus in the parking lot of a motel.

According to the audio, Scott -- seen here in Toronto 2 days before his death in a pic with a fan -- was not breathing and dispatchers conveyed the musician appeared to have gone into cardiac arrest.

TMZ broke the story ... Scott died in his sleep. The underlying cause of death has not been determined.

6:20 AM PST -- An official statement on Weiland's Instagram page says the singer passed away in his sleep.

Rock star Scott Weiland was found dead on his tour bus in Minnesota ... TMZ has learned.

Weiland was on tour with his band Scott Weiland & The Wildabouts ... they were supposed to play the Medina Ballroom tonight, but the show was cancelled. A source connected to the band tells us Scott was found Thursday night on the bus around 9 PM.

Police surrounded the bus, which was parked outside a motel in the town of Bloomington, MN. The Hennepin County Coroner now has Weiland's body.

The former lead singer for Stone Temple Pilots and Velvet Revolver famously battled substance abuse for years. We're told he died in his sleep but it's unclear what caused his death.

Scott was 48.
