CLAYTON • A shooting near Washington University that left a woman injured and prompted a campus alert may have stemmed from a road rage incident.

Investigators were looking for a man driving a black SUV Wednesday afternoon, saying he fired shots at the occupants of a silver car on Forsyth Boulevard near the campus' student union building.

A woman inside the car was struck in the forearm and treated at the scene. She was later taken to a hospital. An email sent to members of the Washington University community identified the victim as an employee of Café Bon Appétit in the Washington University School of Medicine.

Meanwhile, the shooter made a U-turn on Forsyth and continued onto Skinker Boulevard.

Police did not say how many shots were fired.

As of late Thursday morning, police had not made an arrest.

Clayton Police Chief Kevin Murphy said the shooting wasn't random.

“The victims indicated that this was a road rage incident,” Murphy said. “We are investigating that as a possibility.”

As of Wednesday evening, police did not believe the shooting had anything to do with nearby Washington University.

The shooting, however did prompt university police to put the campus on lockdown. Faculty, students and staff were sent alerts telling them to find a secure location and stay there.

Nearby Forsyth School, a private school in St. Louis, was also put on lockdown for a time after the shooting.

All Clayton schools suspended recess and outdoor activity and were keeping students inside immediately after the shooting.

Wednesday's shooting marks the third gun-related incident near Washington University properties to prompt a campus alert in the past several weeks.

In a shooting earlier this month, a teen was injured near the Washington University medical campus adjacent to Barnes-Jewish Hospital. That also prompted an alert, though it did not in the end appear to be connected to the university.

And last month, Washington University briefly issued an emergency alert because of a report of gunfire along the MetroLink tracks near its North Campus facility at 700 Rosedale Avenue in St. Louis.
