Authorities have charged an Ocean County man with sexually assaulting and killing his new girlfriend's 2-year-old daughter.
Camden County prosecutors said Friday that 22-year-old Michael Disporto Jr., of Manahawkin, was charged Thursday.
Authorities say the girl died Tuesday from blunt force trauma to the head.
The girl's mother, Amber Bobo, has been charged with second-degree endangering the welfare of a child.
Investigators say that Bobo noticed injuries on the girl at her Gloucester home and suggested taking her to the hospital, but she waited seven hours because Disporto waved her off.
Authorities say an ambulance responded to a home in Gloucester on Sunday evening and the girl was taken to the hospital, where she died two days later.
The child was not immediately identified by officials.
Disporto was being held on $1.5 million bail. It wasn't immediately clear if he and Bobo had attorneys to comment for them.
Investigators say in a probable cause statement that Disporto and Bobo had been dating for two weeks.
