Fox Executive Gavin Smith Missing

Gavin Smith, a distribution executive for 20th Century Fox, has been missing since Tuesday, according to the Los Angeles County Sheriff's Department.

Smith was last seen Tuesday at a friend's house in Oak Park between 9-10 p.m., according to the sheriff's department. He left in a black 2000 Mercedes 420E that has padded storage racks on the roof and tinted windows. He hasn't been heard from since. His license plate number is 6EKT044.

Smith, 57, is described by the sheriff's department as 6 feet, 6 inches tall and weighing 210 pounds. He has a goatee, gray hair with blonde highlights and green eyes. He has a 5-inch scar on his calf and a 4-inch scar on his inner right wrist. Officials said he was last seen wearing purple pants and black and gray shoes.

The sheriff's department told ABC7 Saturday that they don't suspect any foul play.

Anyone with information on Smith should contact the Sheriff's Homicide Bureau at 323-890-5500.

Smith works for Fox out of his Calabasas office. He is the branch manager for theaters in Dallas and Oklahoma City, according to the Hollywood Reporter.

He was a member of UCLA's 1975 national championship men's basketball team, the last title won by legendary Bruin head coach John Wooden.

Smith's sister, Tara Addeo, came to Los Angeles from from Nevada to aid in the search.

"This is so surreal,'' Addeo told KCAL9 Saturday. "There are no words to describe how you feel when you're in this situation. My flight here was very sad. I wish I wasn't here under these circumstances. But we are here and we're trying our best to deal with this as a family.''

Smith's son, Evan Smith, was a forward on USC basketball team this past season. The younger Smith turned to Twitter Saturday in an effort to help find his father. "

Please help me find my dad Gavin Smith,'' he tweeted. "More people looking the better.''

Smith has worked for Fox for nearly 18 years. "We are very concerned about Gavin,'' said Chris Aronson, president of Fox distribution. "We are actively doing what we can to assist the L.A. sheriff's department.''
