Police said that three people were taken to the hospital and treated for non-life threatening injuries. The victims include a 26-year-old woman, a 23-year-old man and an 18-year-old man, authorities said.

The shooter apparently fired several rounds into a crowd of people gathered in the 600 block of University Avenue, investigators said. 

Witnesses said when people heard the shots fired, everyone ran, but it was unclear from which direction the shots were fired from.

"I heard three gun shots and watched everybody take off down the street as fast as they could," a witness said.

A dispatcher at the Dane County Communications Center confirmed that a shooting was reported at 1:05 a.m. outside of a University Avenue bar, which is located steps away from the campus. 

University Avenue was blocked off from Frances Street to Lake Street as authorities investigated.

Madison police are leading the investigation and are calling the case an attempted homicide.

"(I didn't expect this) here," a witness said. "Not on a college campus with a bunch of kids. That's not right, on a Friday night and on graduation, everybody is having a good time."

None of the injured were students at UW, but Dean of Students Lori Berquam said she was horrified by news of a shooting near campus.

"Madison is generally a safe community and this news is jarring," Berquam said in a news release. "I’d encourage our campus community to step forward with any information they have available."

Detectives declined to speak with the media and instead released an incident report early Saturday.

Berquam and University Health Services counselors will be available to speak to students or family members who would like to discuss the incident at 12 p.m. on Saturday in the On Wisconsin Room of the Red Gym.

“My thoughts go out to those injured in this incident, and I also understand that many students may have been affected as witnesses," Berquam said in a news release. "I’d encourage you to seek support from University Health Services (Saturday), if needed."

The shooter is described as a black man, between 20 and 25 years old,  about 5 feet 9 inches to 6 feet tall.?

There is no known motive for the shooting at this time, and anyone with information is asked to call Madison Area Crime Stoppers at 608-266-6014.
