RIP

The Ohio State University wrestling team has decided to pay tribute to former teammate Kosta Karageorge by putting his initials on their singlets next season ... TMZ Sports has learned.

Karageorge's body was found near the OSU campus on Sunday -- and officials says it appears he died from a self-inflicted gunshot wound. The 22-year-old wrestler and football player had a history of concussions.

We spoke with Ohio State University wrestler Josh Fox who tells us Kosta was beloved by his teammates -- which is why they've decided to put "KK" on their singlets to honor him next season.

"He was the kind of guy that if you were in a brawl, he would be the last one standing because he refused to quit or give up," Fox says.

The LAPD has submitted the Casey Kasem elder abuse investigation to the L.A. County D.A. and it targets Casey's widow Jean ... TMZ has learned.

TMZ broke the story ... an investigation was launched after Casey's kids filed a police report claiming Jean caused Casey to get bed sores that became infected and contributed to his death.

The kids claim Jean was more interested in keeping their dad from them than protecting him, which is why they say she took Casey on a wild, multi-state car ride shortly before his death.

Our law enforcement sources tell us it's unlikely the D.A. will file charges against Jean because there's not enough available evidence. The kids have been fighting for a full autopsy but Jean has resisted.

Casey's body is still rotting in Norway. It has not been buried or even embalmed.

The D.A. says it does not have the case yet, but our LAPD sources say it has been submitted.

The legendary DJ died last June.

Paul Walker fans paid tribute to the deceased actor Sunday on the one year anniversary of his death ... by appearing in droves at the site of the crash.

Hundreds huddled around the crash zone to leave flowers and pay their respects ... but the rain put a damper on candle lighting.

There was a heavy police presence -- it's unclear why -- but it went down without incident.

Walker was the passenger in a Porsche last year when the driver of the car, Roger Rodas, lost control and crashed into a tree. The car instantly burst into flames with both men inside.

Chespirito -- a.k.a. Roberto Gomez Bolanos -- died Friday in Mexico.

The iconic comedian passed away at his home ... according to Televisa -- the company he worked with for most of his career.

Bolanos was beloved for his main character role on the long running show "El Chavo del Ocho" ... as well as his run as superhero "El Chapulin Colorado."

Mexican President Enrique Pena Nieto tweeted, "Mexico has lost an icon whose work has transcended generations and borders."

He was 85 years old.

Fun Fact: The Bumblebee man character on "The Simpsons" was inspired by Chespirito.

"Real World" star Ryan Knight's autopsy was completed Friday morning ... and no immediate cause of death was found -- but police say he had been complaining about stomach issues.

Police in Kenosha, WI say they attempted to revive Knight when they arrived at his friends home yesterday morning ... but they were unsuccessful. They say there were no obvious signs of injuries to Knight -- but according to Knight's father he had complained about stomach issues in the past 2 days.

Cops also say no drugs were found on scene ... even though they were told he had been "partying hard" the night before.

As we previously reported ... Knight was out Wednesday night with a bunch of people and ended up at a friend's house where he was discovered dead and covered in vomit. Friends tell us he had taken "some pills" but they were not specific.

Ryan Knight -- a castmate on the 2010 "Real World New Orleans" -- has died and close friends tell TMZ it was on the heels of a night of partying.

Several of Ryan's friends tell TMZ ... he was out partying Wednesday night with a bunch of people and ended up at a friend's house. We're told a friend found him dead Thursday morning. The friend said he had choked on his own vomit.

Several people who were in contact with Knight while he was partying tell us he had taken "some pills" but they were not specific.

Friends tell us Ryan was upbeat Wednesday night. He was saying he was dating someone new who made him extremely happy.

It's the second "Real World/Road Rules Challenge" death this month ... Diem Brown died a few weeks ago.

Ryan was 29.

Casey Kasem wanted to be buried at Forest Lawn Cemetery in L.A. because he felt that was his path to reincarnation ... this according to his longtime friend and security guard.

Rick Hernandez says he worked as the Executive Security Officer for Casey and his family for years, and became one of the famed DJ's closest friends.

Hernandez wrote a letter to the judge in the case Casey's daughter filed to bring her dad's body back from Norway, where it's been rotting since August.

Hernandez says in the letter ... one day he asked Casey if he believed in God or the afterlife. He says Casey responded ... he believed in reincarnation. Hernandez asked if he planned to be cremated or buried, and Kasem responded that he wanted to be buried and specified Forest Lawn.

The letter wasn't enough to sway the judge, who ruled Kerri had no authority to undermine Casey's wife Jean, who has kept the body in a Norway mortuary for 3 months.

Former Washington D.C. mayor Marion Barry -- who became nationally famous after an epic cocaine bust that did not derail his career -- died Sunday morning at 78.

Barry served 4 terms as Mayor, but his defining moment for most people is what he did in a hotel room during his tenure ... smoking crack with a young woman, and as FBI barged in the room screaming, "She set me up!"

Barry -- who was a folk hero in D.C. -- became the butt of jokes and almost a staple punchline on shows like "SNL."

But after serving time for drug possession, he became mayor once again.

Barry became a paradigm of politicians … how they could do wrong, yet still remain popular with the electorate.

Cause of death has not been disclosed.

G.R.L. singer Simone Battle had just a few thousand dollars to her name when she committed suicide ... but her family claims there could be much more pouring in ... from lucrative contracts she signed shortly before her death.

Battle had just $6,000 in cash to her name when she died, according to court docs filed by her mother, Donna Morgan. But Morgan claims Battle also had deals with Sony, Coca-Cola and other companies and the estate will be getting lots of money from the deals.

Here's the problem ... Sony, Coke and the others won't give Morgan the contracts unless she's appointed administrator of Simone's estate. So she's applied, and her petition is pending.

TMZ broke the story ... Battle hanged herself in her bedroom Sept. 5th. Friends and family said she may have been depressed over money problems.

Mike Nichols -- the legendary director who won the Oscar in 1968 for the classic film "The Graduate" -- died suddenly on Wednesday night. He was 83.

Nichols -- who was married to Diane Sawyer for the last 26 years -- is one of the few people to have won an Emmy, a Tony, a Grammy and an Oscar. His best known films include "Who's Afraid of Virginia Woolf?," "Working Girl," "Silkwood" and "The Birdcage."

Nichols was also a prolific stage director, having helmed Neil Simon's "Barefoot in the Park," "The Odd Couple," and Arthur Miller's "Death of a Salesman" ... just two years ago. He also directed the critically acclaimed HBO miniseries "Angels in America."

Nichols is survived by three children and four grandchildren.

Casey Kasem is rotting in Norway because of his own flesh and blood -- his daughter -- so claims Casey's widow, who has gone to court so she can put Casey in his place for good.

TMZ first reported ... Casey's remains have been stagnating in Oslo for 3 months, and he's been dead for 5. Kerri filed legal docs recently asking for an order allowing her to bring the body of her father back to the U.S. for an autopsy -- something the LAPD wants for its elder abuse probe targeting Jean.

Now Jean has fired back saying Kerri is the obstructionist that is preventing a proper burial.

Problem is ... Jean's argument makes no sense. She's fighting Kerri on the one hand, saying Kerri's U.S. lawsuit is BS because our courts can't force Norway to do anything, yet on the other hand she seems to be saying Kerri's lawsuit is preventing Casey's burial. She can't have it both ways.

Kerri thinks Jean is full of it and the reason she's dragging her feet is so the body decays to the point the Coroner won't be able to pin the blame on her for the infection that led to his death.

Jimmy Ruffin, the crooner who was a staple in Motown for decades, has passed away at the age of 78.

Ruffin reached legendary Motown status in 1966 with his hit "What Becomes of the Brokenhearted" ... and had incredible staying power, hitting the Top 10 yet again with "Hold On To My Love" in 1980.

Ruffin's family ties were just as impressive ... his younger brother, David Ruffin, was the lead singer of The Temptations. David was inducted into the Rock and Roll Hall of Fame in 1989.

Ruffin's 2 kids -- Philicia and Jimmy Lee -- confirmed that he passed Monday at his home in Las Vegas.

Brokenhearted indeed.

The father of the late "Real Housewives" star Russell Armstrong will finally get photographic evidence to answer the question he's been asking for 3 years ... "Was my son murdered?"

The L.A. County Coroner has agreed to turn over pics, negatives, videos and X-rays to Louie Armstrong and his lawyers ... provided they keep the evidence under wraps.

The elder Armstrong has never believed his son took his own life. Russell was in financial straits -- owing a ton of money to business associates -- so when Armstrong was found hanging from an electrical cord Aug. 15, 2011, his dad immediately suspected foul play.

"American Idol" singer Michael Johns died from an enlarged heart, but a "fatty liver" contributed to his death ... this according to the Coroner's report.

The 35-year-old singer died suddenly Aug. 1 after his leg became swollen and bruised ... reportedly from a sprained ankle. Family sources claimed the injury had triggered a blood clot, but his best friend claimed the singer drank himself to death.

The Orange County Coroner's report concludes Johns died of natural causes -- the result of a disease called dilated cardiomyopathy, a condition that inhibits the flow of blood to the body. The disease caused his heart to enlarge.

As for the "fatty liver" ... it can be caused by excessive alcohol intake, but there are other causes as well. Law enforcement told us ... Johns often drank to excess and did so hours before he died.

Timbaland clearly thinks Lifetime deserves every ounce of crap being flung their way for the Aaliyah biopic that premiered Saturday ... and during his attack on the network, no digital punches were pulled.

The rapper/producer went on a social media rampage last night urging people to boycott the "Aaliyah: The Princess of R&B"... using a slew of hilarious memes.

Once the movie was over -- Timbo had no problem gloating to fans who watched the flick anyway -- taunting them and the network with a funny video post.

Timbaland wasn't the only celebrity who had choice words for the movie ... DL Hughley also chimed in -- saying, "Aaliyah is the Soul Plane of Lifetime!"

Glen A. Larson -- who created the hit shows "Magnum P.I.", "Knight Rider" and "Quincy M.E." -- has died from esophageal cancer at the age of 77.

The incredibly successful writer died Friday night at UCLA Medical Center ... according to his son James.

Larson was one of the most prolific producers of the '70s and '80s ... creating a string of iconic hit shows -- including "Battlestar Galactica," "The Fall Guy," "B.J. and the Bear," and "Buck Rogers in the 25th Century."

He also wrote the original "Six Million Dollar Man" pilot and TV movies.

In case you're wondering ... Quincy, Magnum, Rider and Fall Guy alone account for 513 hours of television -- as well as 21 combined seasons from 1976-88.

Safe to say this guy helped define an entire generation of TV watchers.
