Gavin Smith Search Continues In Sylmar, Calif. (VIDEO)

Friends and family of missing Fox executive Gavin Smith canvassed Sylmar, Calif. Sunday, plastering posters of his face and the black Mercedes he was last seen driving on storefronts and restaurants around town.

The family was working on a tip from investigators who had said that a cellphone tower in the area had received the last ping from Smith's mobile phone, reports CBS2.

However, the canvass doesn't indicate a new development in the search for Smith, said Los Angeles Sheriff's Department spokesman Steve Whitmore to the Los Angeles Times. Whitmore told the Times that Sylmar had "no significance" and that "there is no new information," but he did praise the family's continued effort to search for Smith.

In all, about 550 flyers were passed out in the area Sunday, reports City News Service.

Investigators served a search warrant on a convicted drug dealer's house in connection with the search for Smith in June. He was reportedly having an affair with Chandrika Creech, the dealer's wife, before he disappeared, according to E! News sources.

When asked about Smith's connection to the Creech household, wife Lisa Smith told CBS2, "I have no comment. I want to find my husband."

Referencing her three sons, Evan, Austin and Dylan, she continued: "They’re looking for their dad and everything else is not important ... We’re on a mission here. We want to find him. Find his car. Find out what happened."

Smith's family has offered a $20,000 reward for information that will lead to the missing executive, and they've set up a website called to help coordinate search efforts. However, it has not been updated since May 17.

Smith is a distribution executive for 20th Century Fox who has worked on films like "Avatar" and "Star Wars." In 1975, he played on UCLA's championship basketball team under legendary Coach John Wooden.

He was last seen wearing purple workout pants and black and gray shoes, as he left the home of a family friend in Oak Park at about 10 p.m. on May 1 in his black Mercedes.

Investigators are asking that anyone with information call (323) 890-5500.
