Mark Spatucci, a 2009 graduate of Midland Park and the father of Greff’s nine-month-old son, is accused of killing her while the infant was in a bassinet in the room, Bergen County Prosecutor John Molinelli said.
He was found late Wednesday in Midland Park and has been charged with murder, felony murder, burglary, endangering the welfare of a child and hindering apprehension, Molinelli said in a press release.
Authorities said Spatucci drove to the home of Greff's parents, entered through a second-floor window and went into her bedroom. Spatucci and Greff got into an argument that turned violent, Molinelli said.
Spatucci allegedly killed Greff and left her lying on her bed. Greff's parents went out Wednesday morning and found her body when they returned at about 11 a.m.
An autopsy is still pending but the cause of death is believed to be asphyxiation, according to authorities. Greff’s parents were sleeping while Spatucci was in the home and did not notice he was there, Molinelli said.
The two began dating in 2011 and had lived together at Spatucci’s Waldwick home. Greff and her son recently returned to live with her parents, Molinelli said.
Spatucci is scheduled to appear in Superior Court Friday. He is being held on $2 million bail in the Bergen County Jail.
