A Texas man is behind bars after shooting and killing his biological daughter's adoptive parents, Lone Star State law enforcement says. Christopher Lopez was suffering from a lone gunshot wound to the face, and Trinette Rayson-Lopez was shot twice in the head and once in the left hand. He will eventually be extradited back to Harris County. "We hope that he is charged to the fullest extent of the law," the adult children told KHOU after the arrest was announced. In an interview with KHOU, the couple's adult children described the 7-year-old girl as an adopted cousin — not a foster child.
