Stewartville, MN (KROC-AM News) - A Stewartville man is facing two felony assault charges stemming from an alleged incident of domestic violence last week.

A criminal complaint filed Friday in Olmsted County Court charges 29-year-old Quenton Robert Koloff with second-degree assault with a dangerous weapon and domestic assault by strangulation. He was released without bail following his formal arrangement on the charges Friday morning.

The court document says Koloff was arrested on Wednesday after Olmsted County Sheriff's deputies responded to a residence in Stewartville and saw a man shove a woman with both hands on her chest. A deputy witnessed the incident after Koloff answered their knock on the front door by yelling at the deputy to leave and slamming the door shut and locking it behind him.

According to the criminal complaint, a woman managed to escape from the home and Koloff eventually came outside and started walking away from the deputies. While he was being detained, the arresting deputy stated that Koloff's behavior would shift from "aggression to calm."

The woman told the deputies that she had confronted Koloff about not spending time with his family and he allegedly responded by choking her and throwing her over the couch onto the ground. The woman stated she could not breathe and that Koloff then grabbed her hair and twisted her neck before choking her for a second time.

The charges also allege that Koloff attempted to jab her with a knife and told her that he was going to kill her as he tried to stab her. Koloff denied the allegations and claimed that the woman had grabbed the knife first and that he had taken it away from her. He also told the deputies that the marks of injuries on her neck and mouth were self-inflicted.

The criminal complaint notes the deputy located a knife with an 8-inch blade on the couch.

Court records show Koloff was sentenced to three years probation for a domestic assault conviction in 2014. He was granted a stay of adjudication and the felony conviction was later downgraded to a misdemeanor offense.
