Celebrity Plastic Surgeon Frank Ryan Dies in Car CrashDr. Frank Ryan, 50, a Beverly Hills plastic surgeon known for his Heidi Montag makeover and work on stars like Gene Simmons, Vince Neil, Adrianne Curry and Shauna Sand, was killed in a car accident yesterday afternoon.

TMZ reports that Ryan's jeep went off the side of the Pacific Coast Highway, smashing onto some rocks. "Lifeguards initially tried to help Ryan, to no avail," TMZ writes. Ryan was trapped in the vehicle with major head injuries; he died at the scene.

Before the accident, Ryan had been hiking near Malibu with his Border Collie, Jill, and shared a photo on Twitter.

New reports claim the plastic surgeon was sending text messages right before the fatal crash. Celebrity publicist Charmaine Blake told PEOPLE that Ryan's family was told by investigators that the Tweeting caused the wreck on Monday. The California Highway Patrol confirms Ryan was texting before the crash, but investigators have not officially determined the cause of the accident.
