A man Christine later married, Justin Rott, told police a different story. He said Christine admitted to going to the house to participate in a drug heist, and when Snider started shooting she didn't hesitate to join in. Rott said Christine told him that it was her, not Snider, who beat Rachael to death with a gun.
When the police finally caught up with Christine in July 2006, she was high on heroin, living in a hotel room strewn with used needles. She and Rott had been holed up in the room for over eight months.
In September 2008, she was convicted of murder and sentenced to life in prison. She is serving her time at a women's penitentiary in Gatesville, Texas.
The question still lingered: Why would she kill her friends?
"I think there's a chance she thought they were pitying her ... but still envied them, because they didn't have to work so hard to be nice, to be accepted," Saltz said. "That's going to create some intense envy and jealousy, bring out the aggression, and the ... wish to punish them for what they have."
Harris, the Houston police sergeant, said the case never fully added up.
"Ultimately it never made sense," he said, when "you look at the brutality of the crime."
Lori Paolilla now lives with the anguish of a mother whose daughter struggled with, and ultimately succumbed to, the harshness of the world around her.
"We represent parents who have teenage children... young adult children who are living in a world that was much different from when I grew up," Paolilla said. "Keep them away from the ones that you know in your heart are going to be the ones that can break them and weaken them and take them down."
