COOL VALLEY, Mo. – A woman working at a McDonald’s in north St. Louis County was shot Wednesday afternoon.

Col. Mark Hall, the Normandy police chief, said the employee was shot in her chest by another woman while outside the fast-food place located in the 1700 block of S. Florissant Road.

Around 1 p.m., police say the suspect pulled up to the drive-thru window where she and the employee got into an argument. The suspect then drove to the back parking lot, spotted the victim outside, and shot her.

The employee’s condition is unknown at this time but is expected to survive, according to the police chief.

“We arrived and discovered that a female victim, an employee of McDonald’s, got into an altercation with someone. She was shot one time. She was conveyed to the hospital for her wounds,” Hall said.

Police do not have information on the suspect yet or her vehicle. Anyone with information is urged to contact the police department.

“This is something this community, Cool Valley, is not used to. We had some issues in this area of people driving erratically, but nothing of this nature. We will be doubling patrols over here,” Hall said.

The investigation is ongoing.
