Texas man set to be executed for killing his infant son

A Texas man with a long history of mental illness who has repeatedly sought to waive his right to appeal his death sentence faced execution Tuesday evening for killing his 3-month-old son more than 16 years ago. Travis Mullis, 38, was condemned for stomping his son Alijah to death in January 2008. Authorities say Mullis, then 21 and living in Brazoria County, drove to nearby Galveston with his son after fighting with his girlfriend.
