Police in Bridgeport say they're now working with the FBI and the Bureau of Alcohol Tobacco and Firearms to track down two men who shot 13 people over the weekend.
Police say the shooting happened early Sunday on Plymouth Street at an illegal party where the hosts were selling alcohol without a license.
Investigators say they don't have a description of the suspects because they were wearing hooded sweatshirts and hid behind some hedges before opening fire.
While one woman suffered a gunshot wound to the face, police say most of the victims were not seriously hurt.
Bridgeport Police Chief AJ Perez says he's planning to crack down on illegal parties with the hope of preventing more shootings like this one.
He says he's going to assign officers each weekend to seek out those gatherings and shut them down.
