Durango police Lt. Ray Shupe said Tuesday they're asking residents if they've seen anything suspicious around the time that Dylan Redwine disappeared last week.
Dylan has been missing since Nov. 19 after arriving at his father's house for a court-ordered visit during Thanksgiving break.
A search of a lake turned up no clues and authorities say they have run out of places to look.
Dylan's mother told ABC News she fears his father may have had something to do with the disappearance. The father has declined to comment.
