Mario G. Vega, 40, Hortonville, was charged with third-degree sexual assault in Waupaca County Circuit Court.
A 30-year-old New London woman told police that she had been at a neighbor’s cookout on Aug. 23 when they were joined by Vega. She said she had been drinking heavily and remembered Vega repeatedly asking her if her boyfriend would be over that night.
The woman returned to her apartment, went to bed and passed out, according to the criminal complaint.
Vega allegedly sexually assaulted her while she was sleeping.
He faces up to 10 years in prison if convicted.
