A Papillion woman that was found guilty of negligent child abuse for the third-degree burns her infant son suffered has been sentenced to a year in jail.

Omaha television station KETV reports that Star Manzo was sentenced on Thursday. Prosecutors say Manzo’s son was six months old when he was badly burned after being left on a heating pad in February. Manzo had left the baby in the care of her boyfriend, a convicted sex offender, when the incident happened.

Investigators originally charged Manzo’s boyfriend, 29-year-old David Coleman of Bellevue, with felony child abuse. But those charges were later dropped for lack of evidence.

Online court records show Coleman has pleaded no contest to negligent child abuse and will be sentenced Dec. 13.
