DURANGO, Colo. - The search for a missing 13-year-old boy near Durango is part of a criminal investigation, as a task force finished searching the home of the boy's father.
Dylan Redwine has been missing for 12 days.
La Plata County Sheriff's spokesman Lt. Ray Shupe said the father, Mark Redwine, is cooperating with the investigation into his son's disappearance and volunteered to give an interview to authorities Thursday afternoon. He was questioned by representatives from the La Plata County Sheriff's Office, Durango Police Department, Bayfield Marshal's Office, FBI and Colorado Bureau of Investigation.
It was not revealed whether the father consented to a polygraph examination.
Dylan Redwine lives with his mother in Colorado Springs but was visiting his father near Durango for Thanksgiving as part of a court order.
Authorities said they don't consider the boy's father a suspect and that they searched his home because it was the last place Dylan was seen.
Authorities say they don't believe Dylan Redwine ran away or that he became lost in the woods.
The task force concluded its door-to-door canvassing that began Tuesday and have shifted its focus to following up on leads and evidence.
"Until we put together any leads or information that leads us in a certain direction, most work is going to take place internally," he said.
