CHANDLER, Ariz. - Police say a man fatally shot his 3-year-old son outside a family gathering in Chandler and then committed suicide.
Detective Seth Tyler says the 25-year-old father walked out of the gathering being held early Sunday at a Chandler home and carried out the shootings in his parked vehicle.
The child was found on his father's lap.
Tyler says investigators hadn't yet uncovered a motive for the murder-suicide.
The gathering was held at the home of a relative of the child's mother.
The father's name hasn't yet been released.
