A woman raped in a Long Island, N.Y., home used her tongue to dial 911 while her hands were bound with duct tape, officials say.

The woman was house-sitting last month for a friend when she was brutally attacked, said James Chalifoux, of the Suffolk County Major Crimes Bureau. Chalifoux said the woman managed to place the 911 call about 10 minutes after the hour-long assault ended.

The woman and her alleged attacker did not know each other, according to Newsday, which first reported the assault.

Patrick O'Sullivan, 20, pleaded not guilty to charges stemming from the attack, including predatory sexual assault, rape, criminal sexual act, sexual abuse, burglary, and two counts of criminal use of firearm.

O'Sullivan allegedly entered the home through an unlocked kitchen door at approximately 11 p.m. on Nov. 20, according to Chalifoux. When the woman discovered O'Sullivan, he pointed a loaded .22-caliber rifle at her, Chalifoux said.

Chalifoux said police seized O'Sullivan's car and recovered a rifle, as well as items taken from the house where the alleged assault took place, including female undergarments.
