Two sisters have been charged in St. Croix County Court with sexually assaulting a man with a pliers and giving him urine to drink.

Valerie M. Bartkey, 24, and Amanda L. Johnson, 17, both of Somerset are each charged with a felony count of second-degree sexual assault by force and misdemeanor counts of battery and criminal damage to property. Johnson is also charged with a misdemeanor count of intimidating a victim.

The felony has a maximum penalty of 25 years in prison. They each are scheduled to make their initial court appearances April 12.

According to court records:

An 18-year-old man told police he was at a Somerset residence Oct. 1 when the sisters punched and kicked him, and later put one of the man’s shoes in the toilet and soaked the other in a sink.

The man said the sisters later brought him a cup of liquid that they said was lemonade and forced him to drink it. It was urine from the sisters.

The man said the sisters later forced him to undress, saying one wanted to have sex with him. Bartkey reportedly pulled and twisted the man’s penis with pliers while Johnson threatened him with a belt. The man said, on a scale of 1 to 10, with 10 the most pain he’d ever experienced, that the incident was 10. Johnson later ripped the man’s shirt to the point at which it would not stay on his body.

Johnson reportedly called the man Oct. 27 and threatened him, saying she would tell authorities he smoked marijuana Oct. 1. The man denied smoking marijuana but said Bartkey and Johnson did.
