ST. LOUIS – Police have made an arrest after a deadly shooting on I-55 in south St. Louis.

Police reported multiple suspects tied to the shooting have contacted police and are in custody as of Friday evening.

The shooting closed off a stretch of the highway at Gasconade briefly Friday afternoon as police were called to investigate a scene at I-55 at South Broadway, backing up traffic for several miles.

Authorities said a 27-year-old man was found with gunshot wounds inside a four-door silver car. The victim has suffered shots to the head and torso. The back passenger window was shot out, though it remains unclear if the vehicle was moving at the time of the shooting.

Bommarito Automotive SkyFOX helicopter was above the scene. Crime scene investigators, emergency medical technicians, and several officers stood on the highway to conduct the investigation and remove the victim from the car.

Construction workers also took in the crime scene from the barrier separating the northbound lanes from the southbound lanes. A major construction project was underway during the shooting.

I-55 closed for roughly two hours at 12:40 p.m. while police investigated the shooting. The interstate has since reopened. Police have not yet identified the victim or released any suspect information.
