When the woman who gave birth to two children with Thomas O. Hill said that she had another on the way, police in Burlington County say, the ex-con insisted on an abortion.
But the woman wanted to keep the pregnancy, police said, and an argument over the issue inside her home on Union Landing Road, in Cinnaminson, turned violent Sunday.
"He got pissed off at her," said Cinnaminson Police Det. Sgt William Covert.
Hill, 24, of Camden, is accused of sexually assaulting the woman in a bedroom where three children, including two of his own, were sleeping, Covert said.
One child allegedly was knocked off a mattress during the assault, Covert added.
"She's claiming he raped her and he says otherwise," Covert said.
The woman, who is four to six weeks pregnant, appeared to have injuries to substantiate those claims, Covert said.
Hill is being held in the Burlington County Jail in Mount Holly on $75,000 bail on charges of sexual assault, aggravated assault, restraint, terroristic threats and endangering the welfare of a child.
According to the New Jersey Department of Corrections, Hill was paroled from prison on Sept. 10, 2009, after serving less than five months on terroristic-threats charges.
