Three victims were hospitalized with non-life-threatening injuries after being struck by gunfire outside of two bars near the University of Wisconsin-Madison campus early Saturday morning, police said.

Ald. Mike Verveer, 4th District, said police told him that at least a half-dozen gunshots were fired outside Segredo and Johnny O's, on the 600 block of University Avenue, shortly after 1 a.m.

Police did not respond to media requests at the time, but posted an incident report on the department's website indicating that the victims were a 26-year-old female, an 18-year-old male, and a 23-year-old male.

Police told Verveer that there may have been a fourth victim who left the scene.

The incident is being treated as an attempted homicide. Police told Verveer that a car was involved, but they weren't sure whether the shots were fired from the vehicle.

A UW student waiting in line outside of Johnny O's, 620 University Ave., said he heard seven or eight gunshots, likely from a vehicle moving down the street. Mike Muoio, who is graduating on Sunday, was about to show his ID to a bouncer at the bar and dove inside when he heard the shots.
