The fatal shooting of a woman in a St. Paul convenience store Monday occurred when she tried to stab a man, according to preliminary scanner traffic.

Police said the shooter was an employee of the market. Investigators have talked to him and have made no arrests as the investigation into the shooting continues.

A man called police about 7:30 p.m. Monday and reported that he shot a woman in the Quick Stop Market on Payne Avenue, near Edgerton Street, according to police emergency scanner dispatches.

Police found a woman who was unconscious and not breathing. Officers “began life-saving measures,” according to the police department.

An officer reported back to dispatchers: “Have medics step it up,” and reported the woman had a gunshot wound to the chest. Paramedics pronounced the woman dead at the store. Her name has not been released.

It’s “unclear” whether the woman was known to people in the store, said Sgt. Mike Ernster, a police spokesman.

“Everyone who police have interviewed is cooperating,” he said.

The store remained closed as of mid-afternoon Tuesday, but disarray could be seen through the front door — it appeared shelving and other merchandise was on the floor.

A man who said he was a relative of the owner of Quick Stop Market declined comment Tuesday.
