OLATHE, Kan. (AP) — A northeast Kansas teenager will spend five years and four months in a juvenile facility for killing his father during a custody exchange.

The Kansas City Star reports the Bonner Springs youth was sentenced in Johnson County on Monday, which was his 16th birthday. He pleaded guilty earlier to second-degree murder.

The fatal shooting occurred in July 2013 outside a Shawnee business where the boy’s mother and stepfather had arranged to turn him over to his 46-year-old father. The mother and stepfather were inside when the teen walked to his father’s car and fired several times with a handgun.

The teen told police and mental health professionals that he had suffered years of emotional, physical and sexual abuse by his father. He was later diagnosed with post-traumatic stress disorder.
