Cops say Davis then killed her two kids, 18-month-old Andolan and Austin, 10, before taking her own life.

Davis drove to Tailgaters Sports Bar & Grill in Glendale where she is accused of starting her violent spree by firing at her husband of 12 years.

The other woman who Davis allegedly shot at was hit in the back of her head as she tried to flee, Glendale police spokesperson Jose Santiago said.

Police have not revealed the woman’s identity, or if she had any relationship with the husband, but the alleged killer’s friend said Davis was convinced that Nolan was cheating.

The 36-year-old woman was hospitalised with non-life-threatening injuries.

Luckily, Nolan was uninjured, but Davis did not stop there.

She drove the two miles to their Phoenix home, then texted her husband to say that she was going to hurt the children, police said.

Davis is even alleged to have sent Nolan a horrific photo of one of her children bleeding from the head.

Dad Nolan reported the threat to cops at the scene of the bar shooting, who raced to the family’s home.

But when police got to the house and forced their way in, they found the dead bodies of mum Davis and her two kids.

Santiago said: “Because we already knew this was a dire situation, officers forced their way into the home, and that’s when they encountered this horrific situation.”

A friend of the alleged killer, Amy Bowers, claimed the mother had been driven crazy by the belief that Nolan had been cheating on her with a co-worker.

She told AZFamily : “This relationship … completely made her lose her mind.”

Bowers added: “They haven’t had anything like this come up before.

“And so I think the shock of that is just a lot for her. She was just, she was not feeling good.

“And she’s been asking for help from everybody. Like it’s not been secret.”

Cops do not know whether the alleged killer’s husband was cheating.

Santiago said: “We do know that they were familiar with one another, and there was some type of relationship.

“How familiar and what type of relationship, that’s unknown at this time.”

Cops have launched an investigation into the bar shooting and murder-suicide.
