SHEBOYGAN - A 19-year-old Grafton man is facing first degree sexual assault charges after drinking at a party and allegedly threatening to cut a woman if she didn't have sex with him.

Anthony J. Zingale, who was also charged with carrying a concealed weapon, could face a maximum sentence of 40 years in prison if convicted of the crimes.

According to the criminal complaint:

Police were called to a Plymouth home at 10:45 p.m. on May 28 by a man who said Zingale attempted to sexually assault his wife at a party.

When police arrived at the home they made contact with Zingale, who immediately put his hands behind his back to be arrested. He told officers that he had been drinking and acknowledged he was underage, but said his mother was at the party as well.

In his version of the story, Zingale told officers he had to go to the bathroom badly, but was embarrassed because a girl was also in the bathroom. He said when he dropped his pants, the woman in the bathroom grabbed for a knife that he had brought into the restroom.

The woman had a different version of what happened. She told officers that she was using the restroom when Zingale came in holding a knife and was fully exposed from the waist down. She said he pressed the knife to her neck and said he would cut her if she didn't have sex with him. The woman told officers she was able to coax Zingale out of the bathroom by saying they should go to the bedroom, and then screamed for help, at which point others at the party came into the home.
