An investigation is underway after three people were shot in Brighton Friday night.

The shooting happened at 10:28 p.m. in the 200 block of Oakmont Street. Brighton Police Chief Ray Hubbart said officers were dispatched to the residential area on a report of a shooting.

When they arrived at the Oakmont Street scene, they found two men face down there. Police then responded to the nearby Exxon gas station in the 4500 block of Bessemer Super Highway where they found the third victim - a woman - also wounded by gunfire. The female victim, authorities said, had fled the Oakmont scene in search of help.

All of the victims were alive when they left the scenes, but authorities said their injuries were serious. The female victim - who was in an Acura SUV - suffered life-threatening injuries.

Brighton police and the Jefferson County Sheriff's Office are investigating. Hubbart said they had no idea what led to the shooting and said no suspects had been identified or arrested.

Investigators were en route to UAB Hospital where they hoped to obtain more information from the victims.
