So sad because this was preventable!
Dr. Frank Ryan was sending a Twitter message about his dog before his fatal car accident!
His ex-girlfriend Charmaine Blake explains:
"He lived up in Malibu on a tiny street and he was texting while driving and he accidentally went over the cliff…people should not text and drive at all."
The California Highway Patrol confirmed that Ryan was texting before the crash, but investigators haven't officially determined the cause of the crash.
As for his border collie, Jill, she survived injuries to the head, eye and paw.
