"Jordie lost his life doing exactly what he loved," Lunn's family said in a statement to Pinkbike.

Lunn was also well known for his crazy biking videos ... with some clips getting millions of views on YouTube.

"Jordie had an incredible 20+ year career as a mountain biker," his family continued. "He will always be cherished for his heart and love that he gave to his family, friends, and fans, as well as the incredible talent that he had on his bikes."

Spoiler alert ... Luke Perry's character just got a touching sendoff on the new season of "Riverdale" ... with the TV show bidding farewell following the actor's death.

A huge stash of Tom Petty treasure -- including his unreleased music -- is back with his family ... because cops didn't let the alleged burglar do him like that.

Law enforcement sources tell TMZ ... a man broke into Petty's San Fernando Valley storage unit last month and swiped at least $100k worth of valuables. Among the jacked items were guitars and other instruments and some guns. Perhaps most significantly, some precious hard drives loaded with Tom's music -- including unreleased tracks -- were stolen.

The good news -- we're told police caught a suspect who confessed to the crime. He's been arrested for burglary.

The late great Grumpy Cat still has one of her 9 lives left ... to fire off a lawsuit at Internet stores allegedly selling counterfeit merchandise.

The late feline's company -- Grumpy Cat Limited -- is suing to stop corporations and all other entities from producing and selling rip-off gear featuring GC's famous name and furry mug.

According to the legal docs ... the official site for Grumpy Cat t-shirts, hats, coffee mugs and more is grumpycats.com, so it wants the court to help shut down all other Internet shops hawking copycat items.

Lil Peep's own decisions to use drugs and follow down a "destructive path" are to blame for his OD ... so says the tour company being sued by Peep's mom for the rapper's death.

A rep for First Access Entertainment tells TMZ ... Peep's accidental drug overdose was a terrible tragedy, but the company "consistently encouraged Peep to stop abusing drugs and to distance himself from the negative influence of the drug users and enablers."

At the end of the day, First Access says, "He was an adult who made his own decisions and opted to follow a different, more destructive path."

Bernie Sanders' daughter-in-law is dead just days after she was diagnosed with cancer ... and on the heels of the Senator's heart attack.

Rainé Riggs died Saturday, according to the Lee & Martin Funeral Home in Burgettstown, PA. That was the very same day Sen. Sanders returned to Vermont after suffering a heart attack on the campaign trail last week.

Rainé's obit says she had just been diagnosed with neuroendocrine cancer 2 days prior to her death. She had fallen mysteriously ill about 3 weeks earlier.

The blow to Sanders' family comes as he tries to recover from heart surgery. As we reported, 78-year-old Bernie was at a campaign event in Vegas last week when he began experiencing chest pains. He was hospitalized there before heading home to Vermont over the weekend.

Rainé was married to Bernie's son, Levi Sanders, and the couple had 3 children. She and Levi reportedly met back in the day when they were both working at an emergency food shelter in Vermont.

Three suspects have been identified in the murder of Joshua Brown -- Botham Jean's neighbor who testified against ex-cop Amber Guyger.

Dallas PD held a press conference Tuesday saying that the three men were from Alexandria, LA and that they'd traveled to Dallas to purchase drugs from Joshua. Cops claim that an argument ensued, and at one point Joshua shot one of the men in the chest.

Police say that one of the three men, Thaddeous Green, fired upon Joshua twice ... ultimately killing him. The suspect who was shot was treated in a local area hospital, and is now in police custody. The 2 others are being sought on warrants for their arrest.

The news comes after mass speculation that Joshua's killing was in retaliation for his recent testimony against Amber ... which helped to secure a guilty conviction of murder. As we reported ... she was sentenced to 10 years in prison for the crime.

Just days later ... Joshua himself had been shot and killed in Dallas, and people were outraged -- with some claiming he was targeted in some way and demanding answers.

Howard Stern's feeling the loss of Cream drummer Ginger Baker, but says he hopes it will lead to a tribute performance from the last surviving member of the British rock supergroup.

As we reported ... Baker died peacefully in a hospital in England Sunday, and Howard shared some of his memories of the drumming sensation as he was leaving Spago in Beverly Hills.

Stern tells us he was in high school when Cream released their final album -- fittingly titled "Goodbye" -- before breaking up ... and it was apparently worse than any breakup he personally went through.

Comedian Rip Taylor -- who served up over-the-top gags for decades -- has died.

Rip's publicist, Harlan Boll, confirmed the news, saying he passed away Sunday in Beverly Hills. No cause of death was released.

Dubbed the "King of Camp and Confetti" and "The Crying Comedian," Rip got his start by appearing on "The Ed Sullivan Show," "The Merv Griffin Show" and lots of other variety talk shows as a comic in the '60s, going on to star on several different game shows as well.

He's perhaps best known for his brief stint hosting "the $1.98 Beauty Show," which had guests compete for the title of the "1.98 Beauty Queen" in a pageant, talent-show format.

Iconic drummer Ginger Baker died in a hospital in England Sunday ... leaving behind one of the greatest rock 'n' roll resumes. Ever.

In late September, Ginger's family announced he was hospitalized with a critical illness, and a few days later asked fans to keep him in their prayers. The family has not revealed what illness he was battling, but said he "passed away peacefully."

Ginger was known as a wild man on the drums from his days playing with Cream members Eric Clapton and Jack Bruce. The group played legendarily long jams during their live shows and defined the psychedelic rock sound of the 1960s.

After Cream broke up, he went on to form another supergroup, Blind Faith ... also with Clapton. He also formed his own jazz-rock band, Ginger Baker's Airforce -- but he was most known for his amazing solos, especially live.

Cassandra Waldon, the very first "Big Brother" contestant to enter the house on the U.S. version, has died.

Cassandra passed away on September 25 ... apparently from injuries related to a car accident in Rome. A source at the United Nations -- where Cassandra worked -- tells TMZ ... she was struck by a car about 2 months ago, and suffered a head injury. We're told she never regained consciousness before her death.

Julie Chen, the host of "Big Brother," remembered Cassandra as a standout houseguest from the debut season in July 2000. Julie posted on Instagram, "Thank you for bringing your intelligence, warmth and wisdom to the Big Brother house Season 1."

She is the answer to the trivia question -- who was first to walk into the 'BB' house? That's kind of a double-edged sword ... as some fan blogs also point out she was first to fall victim to the so-called "First to Enter Curse."

No one who's entered first -- on the U.S. or Canadian (non-'Celebrity') versions -- has ever won the competition. Cassandra finished 6th out of 10 houseguests.

Cassandra worked at the UN as its Director of Communications for the International Fund for Agricultural Development. She was living and working in Rome when the accident happened.

We're told her funeral will be held next weekend in her home state of Maryland. Cassandra was 56.

Diahann Carroll -- the iconic, pioneering actress for African-Americans -- and star of the groundbreaking sitcom, "Julia," died Friday from cancer at her home in Los Angeles.

Diahann -- who was diagnosed with breast cancer in 1997 -- was a native New Yorker, born in the Bronx, who first made it big on Broadway. She won a Tony Award for Best Leading Actress in a Musical in 1962 for her role in "No Strings."

Her huge break in Hollywood came as the star of NBC's "Julia" ... the first network series to have a black actress as the lead character. Diahann played a widowed nurse who was raising a son. The show premiered in 1968 and ran for 3 seasons -- and Diahann earned an Emmy nomination and won a Golden Globe for the role.

Air Force's beloved falcon mascot, Aurora, took her last flight on Wednesday ... the school announced the iconic bird has died. She was 23.

Aurora -- a rare white phase gyrfalcon -- played a huge role at Air Force sporting events over the years and was touted as "an ambassador for all falcons."

"We are deeply saddened to announce that Aurora passed away earlier today," the Academy said in a statement. "Aurora was the Academy’s longest-serving live mascot. In her 23 years at USAFA, she interacted with tens of thousands of people at sporting venues and military and community events."

USAFA credits Aurora for "helping us educate the public on the importance of these majestic birds."

On the heels of criminal charges being filed in the death of Mac Miller, 6 men have just been arrested in connection with the fatal OD of HQ Trivia co-founder and CEO Colin Kroll ... and federal authorities say the men went to great lengths to avoid getting caught.

The group allegedly peddled coke and heroin daily in NYC through their drug delivery service called "Mike's Candyshop," which counted Kroll as a customer ... this according to the U.S. Attorney's Office for the Southern District of New York.

According to the feds, the NYPD and DEA's investigation turned up an illicit enterprise that allegedly allowed people to order heroin and coke to their doorstep as simply as if they were ordering a pizza.

In the indictment ... one of the victims identified as "Victim 1" -- TMZ's confirmed it's Kroll -- died from a cocktail of drugs that included heroin and coke allegedly provided by Mike's Candyshop.

What's more ... the feds claim Mike's changed its phone number twice to avoid getting caught. Still, the delivery service continued operating its on-demand drug service.

Kim Shattuck -- the lead singer and bassist for The Muffs -- is dead after a two-year battle with ALS.

Kim's husband shared the sad news Wednesday in a social media tribute to his late wife ... saying, "This morning the love of my life Kim passed peacefully in her sleep after a two year struggle with ALS."

Her husband continued ... "I am the man I am today because of her. She will live with all of us through her music, our shared memories and in her fierce creative spirit. I love you always my Kimmy. Thank you for sharing your life with me."

All 3 men arrested in connection with Mac Miller's death have now been indicted, and accused of dealing counterfeit oxycodone that caused the rapper's death.

A federal grand jury handed up the indictments of Cameron Pettit, Stephen Walter and Ryan Reavis in a California federal court. The indictment backs up what TMZ first reported ... that Mac ordered 10 "blues" -- a street term for oxycodone -- as well cocaine and Xanax. Prosecutors say that instead of getting oxycodone on Sept. 5, 2018 ... the pills Mac received were counterfeit and contained fentanyl ... the powerful synthetic opioid 50 times more potent than heroin.

The feds say Mac crushed the pills, snorted them and died.

As we reported ... feds say the deal went down like this: Mac ordered from Pettit, Pettit ordered from Walter ... and Reavis was the mule, delivering the drugs from Walter to Pettit.
