PHOENIX - Phoenix police said a 45-year-old man intentionally drove his truck onto a sidewalk and hit a woman and an 11-year-old girl Wednesday night near 41st Street and Jomax Road.

According to police, after hitting the woman and child, Trent Ferree backed up his truck and hit the woman a second time. He struck the woman again before witnesses pulled him from his truck and held him for police.

The woman was taken to a hospital where she later died. The girl was taken to a hospital with "less serious injuries," police said.

According to the Maricopa County Sheriff's Office, the woman was the wife of deputy and the girl is his daughter.

MCSO released a statement Thursday:

We are saddened by the tragic death of the wife, and injuries to the daughter, of Deputy Sergeant Steve Chervenak. Our oneMCSO team is with Sergeant Chervenak and his family to ensure we provide all possible support during this difficult time.

Chervenak has been with MCSO since 2007.

Police said evidence shows it was a random act of violence and the victims were not targeted because of their relation to Deputy Sgt. Chervenak.

Ferree attempted to strike two others walking in the neighborhood earlier in the night, police said.

According to police, Ferree will be booked for one count of first-degree murder and three counts of attempted first-degree murder.

Mike Steinberg witnessed the fatal incident while coming home from Prescott. He immediately ran over to help.

"I was yelling at him to stop and he actually stopped," Steinberg said. "That was the time when the firefighter across the street came out of his house, took the guy out of the vehicle and he was telling me to stay on top of the guy to make sure he didn't move while he went over to the woman."
