CBS 4 in Denver is reporting Luke has been found safe in Canada and the suspect is in custody. No other details have been released.
An Amber Alert has been issued for a 3-year-old boy who may be headed to or already in Missouri.
Luke Turner is a white male with blonde hair and blue eyes, 3 feet tall, 28 pound and was last seen wearing a royal blue "Lightning McQueen" shirt with blue swim shorts.
Authorities say Luke's father, 52-year-old Monte Turner, burst into Luke's mother's home, tazed and pepper sprayed the mother, and physically removed Luke from the home.
Turner is currently under a protection order requiring no contact with Luke after he had previously abducted the child.
The two may be on their way to a residence in Willard, Missouri, via I-70.
Turner is described as a white male with brown hair and blue eyes, 6'2", 210 pounds and was last seen wearing a long-sleeved dark blue shirt and blue jeans.
Police say the two may be in a maroon 2001 Dodge Caravan with Colorado tag 576-ZXY, a brown 1997 Ford F350 pickup with Colorado tag 541-YLH or a 1993 Jeep Grand Cherokee with Colorado tag 837-UHS.
Turner's father, Ronald Turner, was arrested early Sunday morning outside Springfield as an accessory to the kidnapping.
