An “emaciated” baby survived many days alone in an apartment in Phoenix, Arizona, after his mother died, according to investigators.

Shocking bodycam footage obtained by the Phoenix Police Department shows the newborn struggling to life after officers knocked down the door during a welfare check on May 14.

Authorities pushed open the front door after an attentive neighbor called 911 to request a welfare check because the mother “had recently given birth to a baby, and had not been seen or heard from for several days,” Phoenix police stated in a press release.

Bodycam footage shows an officer gazing into the residence through an open window and informing the other first responders, “The baby’s here, dude.” “And the baby is still alive.”

While looking through the window, cops noticed the mother lying “motionless on the floor.”

Police knocked down the door and found the “visibly emaciated” baby sleeping on an adjacent bed, according to the release.

“Officers rushed to the front door and forced it open,” Sergeant Brian Bower stated in the press statement. “Officers swiftly rescued the infant and met with Phoenix Fire personnel, who took the child to the hospital in serious condition.”

According to police, the baby’s condition has improved, and they are expected to make a “full recovery” after receiving “lifesaving care.”

Bower applauded the cops’ actions, telling KPHO, “It’s because of the officers’ smart, immediate actions, as well as the neighbors seeing something unusual and calling for help.”

“It wasn’t learned until well after the fact from doctors and staff at the hospital that if the police officers didn’t immediately provide aide and didn’t immediately go into the apartment, the child may not have survived much longer,” according to him.

According to the news release, authorities are currently examining the mother’s cause and manner of death. The Department of Child Safety is also assisting the detectives and the child’s family.
