A father is suspected of running over and killing another dad after a fight escalated outside of Canyon Springs Elementary School in north Phoenix Monday, according to Phoenix police and court documents.

Anthony Parrinello, 31, was arrested on suspicion of second-degree murder, according to Sgt. Trent Crump, a spokesman for the Phoenix Police Department.

Parrinello got into a fight with Carmelo D'Alessandro, 42, at the school near 45th Avenue and Anthem Way on Monday, Crump said.

Parrinello wanted to settle the disagreement with a fight at a nearby Walmart. However, D'Alessandro decided to walk home instead of continue the fight, according to Maricopa County Superior Court documents.
