An execution date has been set for a Texas man who set a senior citizen on fire, leading to her death.
Matthew Johnson will be put to death in May. That’s almost exactly 13-years after the attack in the Dallas suburb of Garland. He walked into a gas station and robbed 76-year old Nancy Harris, who was working the register.
The arrest report shows that, for no reason, he poured lighter fluid on the grandmother and set her on fire.
