The family had planned a search for Smith in mid-May and hoped to enlist the public's help in the search, but the mission was canceled because a search area had not been pinpointed.

The Los Angeles County Sheriff's Department has not yet had any breaks in the case, the department told TheWrap last week.

The family has set up a website, Find Gavin Smith, to collect tips in the case.

A spokesman for Smith's family and the Los Angeles County Sheriff's Department have not yet responded to TheWrap's requests for comment.
