Tillman died on Tuesday, Davis told the Ventura County Star, after developing a heart muscle disease this summer. He was traveling to a pet hospital when he died.
Tillman became a star after a video of him skateboarding around like a champion went viral in 2007, and that video ended up in an iPhone advertisement:
Tillman was a “total ham,” Davis said last year. “He’s been the star of a reality show, and he’s skated in Times Square, and nothing seems to faze him. I get more nervous than he does.”
