The woman accused of stabbing her boyfriend Tuesday because she was tired of his alleged drug use has been charged.

Thia Frae Olson, 40, of Austin was charged Thursday in Mower County court with felony second-degree assault with a dangerous weapon causing substantial bodily harm.

At about 11:30 a.m. Tuesday, Austin Police Officers responded to the 900 block of Fourth Street Southwest for a call of an injured man with a gash on his back and his shirt off flagging down cars. He then apparently got into a white van that was backing out of the driveway, according to court records.

Officers saw a deep incision wound on his back, and the victim was pale and profusely sweating.

The victim said he was having trouble breathing.

He said he was with Olson at the time and the two had been fighting when he was stabbed.

Officers first saw Olson holding pressure on the victim’s wound but then she stepped back and stood in the driveway. Initially, the victim said the cut came from a piece of wood that looked like a knife, adding he fell on a board with an unknown sharp object.

Olson told officers she didn’t know how the victim was injured, but she said they were fighting in the upstairs bathroom and a door was damaged. Officers looked at the scene and noticed significant damage to the bathroom doorframe and saw the lock was still engaged, meaning the door had been forced open and the frame broken.

They also saw an apparent fresh puncture or stab mark on the door itself, consistent to being struck with a sharp instrument, the report said.

According to court records, Olson admitted to losing her temper and stabbing the victim because she was “sick and tired of his drug use and of him bringing drugs into her home.” She identified the knife she used to officers and it was consistent in size and shape to the damage observed on the bathroom door.

The victim was taken to Mayo Clinic Health System in Austin and then flown to St. Marys Hospital in Rochester with a collapsed lung.

Olson’s next court date is on May 5.
