Last week, 20th Century Fox movie executive Gavin Smith was staying at a friend's house in Oak Park, CA, but drove off in his black Mercedes around 10 p.m. and never came back (video below).
Smith was reported missing by his wife on Wednesday morning when he failed to pick up his son to take him to school and did not call into work or his family.
Evan Smith, Gavin's eldest son, told ABC News: "My dad had no reason to leave. No reason at all."
Smith was staying with a family friend in Oak Park, CA. He had returned earlier that that day from a movie convention in Las Vegas, and was supposed to stay the night there, but left that home without warning.
The Smiths told ABC News that Gavin Smith's cell phone charger, shaving kit, and other belongings were all at the friend's house where he was staying.
