Disturbing moment Lori Vallow LAUGHS hours after husband’s death as Tylee says she protected mom from ex with bat

LORI Vallow was filmed laughing with an investigator hours after her estranged husband was shot dead by her brother in Arizona.

Chilling video released this week shows the "cult mom" engaged in a friendly interview with a Chandler Police Department official on July 11, 2019.

The video was filmed shortly after Lori's fourth husband Charles Vallow was shot and killed by her brother Alex Cox during a custody dispute at her home.

Police initially determined that Cox acted in self-defense, but the case was reopened later that year when Lori's children Tylee Ryan, 16, and Joshua "JJ" Vallow, seven, were reported missing.

Prosecutors charged Lori with conspiracy to murder Charles in June of this year, shortly after she was indicted over the deaths of her kids.

In the video released among a bevy of case files this week, Lori is heard talking and laughing about Tylee before explaining the events that preceded the shooting.

She said she asked Cox to come to her house because she feared Charles would "ambush" her when he arrived to pick up their adoptive son JJ.

"I was expecting kind of an ambush for him to come over," Lori told the investigator. "Be just mean. 'It’s my house, I’m on the lease. I’m going to stay here.'"

"He’s acting really weird like he’s plotting something," she added. "Why are you even here? What did you come here for?"

Lori went on to explain her marital issues with Charles, who had filed to divorce her months earlier.
