DURANGO, Colo. (CBS4)- Investigators in La Plata County have been flooded with tips from callers after the parents of missing teen Dylan Redwine appeared on Dr. Phil.

Dr. Phil interviewed Dylan’s parents, Mark and Elaine, on Tuesday afternoon’s show. Both parents blamed each other for Dylan’s disappearance.

On Wednesday, Dr. Phil interviews Dylan’s older brother, Cory. He won’t even call his father “Dad,” referring instead to him as “Mark.”

Cory also voices some suspicions.

“I think that Mark has something to do with it. I think he’s either got him hidden out or done something. I strongly think he’s involved,” said Cory. “He hasn’t done a single thing since Dylan has been gone.”
