with the news pouring in from Texas where a gunman disguised as a deliveryman forced his way into a home. Six members of the same family were killed. Tonight we are laerng more about the alleged shooter as we also learned how a teenager did something that may have saved lives. ABC's Ryan Owens has been tracking the breaking news today. Reporter: A suburban community shattered. After a dinner-time car chase Wednesday paralyzing this quiet neighborhood north of Houston. A murder suspect finally stops in the cul-de-sac. For nearly four hours, a standoff. The suspect with a gun to his head. The police surrounding him in armored vehicles. 33-year-old Ron Haskell ultimately gives up and tonight he's charged with capital murder, accused of executing six members of this family. I have not seen something this horrific. Reporter: Authorities say Haskell tied up and murdered Steven and Katie stay and four of their young children. He also shot the couple's 15-year-old daughter in the head. She played dead until he left, then called 911, telling police the suspect was headed to her grandparents' house to kill them, too. Officers got there first. She absolutely saved the lives of her family members. I mean, she is the hero. Reporter: And she's expected to be okay. The lone survivor from her family recognized the gunman who was dressed as a FedEx deliveryman, because he is her uncle. Police say Haskell came here looking for his ex-wife. They just divorced on Valentine's day. Haskell had been arrested for assaulting his wife before and until last year she had a protective order against him. It's not just his ex-wife. His own mother filed a domestic violence complaint against him just last week. Still, no one suspected the family that lived in this home with all of those young children might also be a target.
