The ruling Wednesday by the state's highest criminal court accelerates the execution process for 25-year-old Travis Mullis. He had to undergo a psychological exam to ensure he was capable of making the request.
A Galveston jury last year decided Mullis should die for sexually assaulting and fatally stomping his infant son. The boy's body was found on a berm along the Galveston seawall.
Mullis surrendered to police in Philadelphia three days after the attack, confessing that crushing the boy's skull was the only way to make him stop crying.
