DURANGO, COLO. (AP) -- The La Plata County Sheriff's Office says leads are dwindling after a month-and-a-half-long search for a 13-year-old boy who was reported missing in southwestern Colorado.

Sheriff's office spokesman Dan Bender says the number of tips coming in from the public regarding the disappearance of Dylan Redwine has dropped from several dozen a day to about two or three per day. But investigators haven't given up on the case.

Dylan has been missing since Nov. 19, a day after arriving at his father's Vallecito home for a court-ordered visit during Thanksgiving break. The boy was living with his mother and brother in Colorado Springs.

His father says he last saw Dylan asleep when he left home early to do some errands. He reported the boy missing that afternoon.
