MADISON, Wis. — An early-morning shooting Sunday at a rooftop party in Wisconsin’s capital left at least 10 people injured, including teenagers, police said.

Nine people were injured by gunfire and a tenth was injured by broken glass at the party at a high-rise apartment in downtown Madison.

All of the injured were taken to hospitals, but none had injuries considered to be life-threatening, according to authorities. Madison police said in a Sunday afternoon update that at least one of the injured remained in a hospital.

The victims ranged in age from 14 to 23.

“It is truly a miracle that no one is dead,” Madison police Chief Shon Barnes said at a news conference. “As a community, our hearts are hurting.”

Police were called to the apartment complex around 12:45 a.m. Sunday.

“These students should have been celebrating summer vacation and not receiving medical treatment,” Barnes said.

The shooting happened near the University of Wisconsin-Madison campus, but university officials said no students were known to be among those injured or involved.

No one was in custody in connection with the shooting as of Sunday.
