(AP) — A 14-year-old northeast Kansas boy is charged with first-degree murder in the shooting death of his father during a custody exchange with the man’s ex-wife.

The teen was charged in the juvenile division of Johnson County District Court on Wednesday, one day after the shooting outside a business in Shawnee.

Police and prosecutors have not commented on a possible motive. The boy’s appointed attorney declined to comment while he continued gathering information.

Authorities have said the boy’s mother and stepfather brought him to the business Tuesday afternoon to exchange custody with the 46-year-old father. Investigators say the boy approached his father’s car and shot him with a handgun.

The Associated Press is not naming the father because of the boy’s age.
