He was found in the home with a self-inflicted gunshot wound. He was taken to Medical City Plano where he was later pronounced dead.

Murphy Police believe Vincent showed up to his father and stepmother's home just after 6 p.m. with another individual and attacked his father and stepmother with several weapons, before turning his gun on himself.

The other person was identified and is cooperating with Murphy police.

The motive for the violence and the circumstances leading up to the shooting are unknown.
