DENVER (CBS4) – The parents of a missing teenager will come together to ask the nation to help find their son.

Dylan Redwine’s parents are divorced and admit they have their differences, but they will appear on Dr. Phil on Tuesday.

CBS4 has talked with Dylan’s mother Elaine and her ex-husband Mark since Dylan’s disappearance. They share custody of the teen.

Dylan disappeared in November while visiting his father in Vallecito. CBS4 talked with Mark Redwine before the taping of the show.

“My ex-wife and I both agree that Dylan’s not the kind of kid that would run away, but I also think that there’s a possibility that Dylan was torn between his parents,” Mark told CBS4.

Dylan turned 14 earlier this month.

The La Plata County Sheriff’s Office and the FBI are still investigating.
