Police: Widower of former Maricopa County attorney killed girlfriend, her mom in shooting
Phoenix police continue to investigate a Christmas Eve shooting that left three people dead, including the alleged gunman, David De Nitto. He was the widower of former Maricopa County Attorney Allister Adel.
Police say De Nitto killed his girlfriend, Maryalice Cash, and her mother, Cynthia Domini, before turning the gun on himself.
Phoenix police Sergeant Philip Krynsky says an argument preceded the shooting.
"The investigation does remain active, but what we can tell you is the early information is that Cash and De Nitto were in a relationship together," he said. "There was a holiday gathering at the home, and that the altercation happened before the shooting happened."
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.
