Ryan Dunn's Family, 'Jackass' Friends Hold Private Memorial Service

Bam Margera, Johnny Knoxville and two 'It's Always Sunny in Philadelphia' stars attended Wednesday's service.

WEST CHESTER, Pennsylvania — Hundreds of Ryan Dunn's friends and family members flooded a suburban Philadelphia funeral home Wednesday for a private memorial service to honor the "Jackass" star, who was killed in a fiery car crash early Monday morning.

Described as "a celebration of Dunn's life," the service in West Chester, Pennsylvania, lasted more than four hours. The daredevil's famous friends who gathered included best friend and "Jackass" cohort Bam Margera — who attended with his wife, Missy, and parents, Phil and April Margera — Johnny Knoxville and "It's Always Sunny in Philadelphia" actors Glenn Howerton and Rob McElhenney.

The Kings of Leon, who became close with Dunn last year, also paid tribute to the star Wednesday night during their show in London's Hyde Park. Frontman Caleb Followill asked the audience to toast "a friend of ours who's passed away," adding, "This is for Ryan," before playing "McFearless," from 2007's Because of the Times.

Earlier in the week, bassist Jared Followill tweeted, "I'm heartbroken to say that our great friend we made over the last 8 months has passed away. Honestly in shock. Devastated. RIP Ryan Dunn."

Accident-reconstruction teams have estimated Dunn's 2007 Porsche 911 GT3 was traveling between 132 and 140 mph in a 55 mph zone when it collided with a guardrail around 2:30 a.m. Monday. The Porsche then went soaring through about 40 yards of trees before hitting one and bursting into flames.

Dunn, who recently celebrated his 34th birthday, will reportedly be buried in Ohio, where he was born. The website for the DellaVecchia, Reilly, Smith and Boyd funeral home, where the service was held, says a public memorial will be announced at a later date. Dunn's obituary requests contributions be sent to Garth Brooks Teammates for Kids, a foundation the country singer started in 1999 to raise money for children's charities.

On Tuesday, a very-distraught Bam Margera spoke to a local Fox affiliate, telling a reporter, "I've never lost anybody that I care about; he's my best friend.

"He was the happiest person, the smartest guy with so much talent," he continued. "He had so many things going for him. ... It is not right."

Bam's mother said she considered Dunn her son. "He's gonna be really missed by everybody," April Margera told NBC News on Tuesday. "[I'm] sick because it's a waste, sick because I loved him, sick because he was talented, sick because I can't believe he's gone."

The "Today" show reported that Dunn's family members flew to West Chester from Ohio and Florida to plan his funeral, telling NBC News, "We are devastated by the loss. Ryan will be greatly missed, but he will forever be in our hearts."

According to a preliminary toxicology report by the Chester County coroner's office, Dunn's blood alcohol level was 0.196, more than twice the 0.08 legal limit in Pennsylvania. The report also says there were no "drugs of abuse" detected in Dunn's system.

The coroner's report lists blunt force trauma and thermal trauma as the official causes of death for Dunn and his passenger, 30-year-old Iraq war vet Zachary Hartwell, who was credited as a production assistant on "Jackass Number Two" and was working with Dunn on his new G4 show, "Proving Ground."

Dunn grew up in New York before moving to West Chester, where he hooked up with Bam's CKY crew. He kicked off his career doing stunts and skateboard tricks in a series of online videos, which eventually led to his part in MTV's "Jackass" in 2000. He also appeared on "Viva La Bam" and "Bam's Unholy Union," in addition to the three big-screen "Jackass" adaptations. He was the star of his own short-lived MTV show, "Homewrecker," and co-hosted G4's "Proving Ground," which premiered last week but has since been pulled off the network's schedule.
