Chanda Vandeslunt is accused of firing a gun while drunk, outside the Prairie Inn and Suites in Holmen on Saturday night.
Vandeslunt said she was shooting at a nearby business sign.
According to the criminal complaint, police said the woman apparently had been arguing with her husband at the Holmen American Legion hall, and decided to leave with a man she had just met there.
They went over to the motel.
Vandeslunt reportedly saw the man carrying the gun, and took the weapon from him. He took back the gun after she fired it into the air four times.
Officers at the scene of a car fire at a nearby Kwik Trip were sent over to check on the gunfire.
