Northwestern student shot at Willye B. White Park in Rogers Park

CHICAGO (CBS) -- A Northwestern University freshman is recovering after getting shot off-campus Monday night in the Rogers Park neighborhood.

The shooting comes as students are preparing for finals and end-of-the-year celebrations.

A 19-year-old woman and a friend were standing in Willye B. White Park, near Howard Street and Ashland Avenue, around 10:15 p.m., when they heard gunshots and started running.

It wasn't until they took cover in a nearby doorway that they realized the 19-year-old as injured.

The victim's friend drove her to St. Francis Hospital, where she was listed in critical but stable condition.

Robbie Staggers heard the shots, but saw nothing.

"It was, like, you know, really loud; boom, boom, boom, boom, boom. It was like it was in my house," Staggers said. "Oh my God, it was so many. I don't even remember how many."

Police counted about 40 shell casings at the scene.

Area 3 detectives are investigating. Police do not know a motive. Northwestern believes the student was not targeted.

"We are heartbroken and outraged that gun violence continues to have such an impact on members of our community and on the greater Chicago area. Please keep this student and their family in your thoughts," the university said in a statement.

Northwestern officials encouraged students to take advantage of free virtual mental health support services, or the university's Counseling and Psychological Services offices. University employees also can take advantage of the Employee Assistance Program.

Hours after the student was shot, police were called back to the scene; this time across the street from where they originally began their investigation, to a nearby parking lot, where someone had shot Sargo Ortiz's car. He had showed up to pick up his landscaping and concrete truck for work, and found a bullet hole in the front windshield, and a shattered driver's side window.

"In the morning, I come and when I see, I think maybe somebody broke in the glass when they tried to steal something in my truck, but now when I see the big glass, I see that somebody shoot it," said Ortiz.

Now he has to pay out of pocket to fix it.

"I think the cost is around to $800, and I lose my day of work," he said. "I need it every day, my truck. Right now, I can't work."

No one was in custody in either incident Tuesday afternoon.
