Arizona police rushed into a home to rescue a 6-month-old infant who had been shot multiple times after a suspect took the child and the child’s mother hostage on Friday, authorities said.

The suspect, identified as 51-year-old Todd Christopher Marchetti, broke into the home on 168th Avenue and Jenan Drive in Surprise at around 3 a.m. and refused to allow the mother and her baby to leave, the Surprise Police Department said. Marchetti was believed to be the child’s father.

Linda Ogle, a friend of the mother, told AZFamily that the victim had moved back in with her parents to escape Marchetti’s alleged abuse. Ogle said Marchetti had planned to torture the victim while her parents were out of town.

"He used an ax to get through one of the windows," Ogle told the station. "He brought duct tape and ropes and different forms of pliers and a couple different butcher knives."

The resourceful mother, however, was able to escape her home around 11:30 a.m. and ask a nearby construction crew for help. Officers responded to a 911 call from the crew.

Upon arriving at the home, police said officers heard multiple rounds of gunfire from inside. One officer fired a round toward the suspect in the home, while other officers burst inside to rescue the infant.
