Late prosecutor’s widower kills girlfriend and her mother in murder-suicide

David DeNitto was married to the late Maricopa County attorney Allister Adel

An Arizona widower fatally shot his girlfriend and her elderly other in an apparent murder-suicide, according to police.

Officials say that David DeNitto shot his girlfriend Maryalice Cash, 47, and her mother Cynthia Domini, 83, inside his home on Christmas Eve.

DeNitto, who was married to the late Maricopa County Attorney Allister Adel, was pronounced dead at the scene. Cash and Domini were rushed to hospital where they died from their wounds.

Investigators say that DeNitto and Cash had been involved in an argument before the violence unfolded.

“It was some kind of fight, some kind of altercation. I don’t know the subject matter,” Phoenix police spokesperson Donna Rossi told NBC News.

Allister Adel was appointed Maricopa’s top prosecutor in 2019, before winning the office in 2020.

She suffered a brain haemorrhage on the night she won the election, and in 2021 was treated for alcohol abuse and eating disorders, according to NBC News.

She died in April 2020 from “health complications” the family said at the time.

“It is impossible to comprehend a tragedy such as this,” Maricopa County Attorney Rachel Mitchell said in a statement on Monday.

“Words cannot adequately express the flood of sorrow. I ask the community to join me in praying for the families affected and, most especially, Allister’s children.

“I also ask that the community surround the families with love, kindness, and a respect for the need for privacy.”
