Chicago (CNN) -- Police at the University of Illinois at Chicago have taken a person into custody in the shooting death of a woman in a hospital garage, the school said Friday.
Police say a man killed his girlfriend in the garage, prompting a lockdown for much of the night, CNN affiliate WLS reported.
Following two searches, including a search of every room in the hospital, university officials resumed normal operations there around 5 a.m., the station reported.
The university said on its website that a "person of interest" had been taken into custody and a weapon recovered. Further details were not immediately available. Campus police referred calls to the school's media relations office, which did not immediately return a telephone message.
