A Christmas Eve shooting in Phoenix has left three dead. Police identified the gunman as the widower of former Maricopa County Attorney Allister Adel. 

Officers responding to a shooting call late Sunday found two women — ages 47 and 83 — who had been fatally shot. Police said 47-year-old David DeNitto, who had been married to Adel, was dead from an apparent self-inflicted gunshot wound. 

Adel resigned as county attorney in March 2022 after drinking-related incidents came to light. She died less than a month later of health complications.

Adel’s successor, County Attorney Rachel Mitchell, released a statement in the wake of Sunday’s shooting, saying it is impossible to comprehend the tragedy.

“I ask the community to join me in praying for the families affected and, most especially, Allister’s children," Mitchell added.
