CHICAGO (WLS) -- A security alert has been issued for the University of Chicago campus after police say a former student stabbed his roommate and then fled.
Police say the stabbing took place about 3 a.m. Saturday in the city's Hyde Park neighborhood. The university confirmed the suspect, Ross Jacobs, is a former graduate student, but has not been enrolled since 2013.
It is not clear what precipitated the attack, but neighborhood residents described Jacobs as a person known for his erratic behavior. Police have been patrolling the area.
"Knowing that he's still out and about and no one knows where he's at, it's really, it's terrifying actually. I hope they find him," said resident Cassie Gamez.
According to the community alert, Jacobs allegedly stabbed his 27-year-old roommate several times before fleeing the apartment they shared in the 5400-block of South Hyde Park Boulevard.
"I've always encountered this guy and I'm always on alert when I see him or approach him or whether he's approaching me," said neighbor Delaney Gentle. "I knew there was something off, it was clear, by his actions were just random. Not of a normal person. He just seemed like he was in his own mind in his own world."
The stabbing victim survived the attack but is in serious condition. Police are warning area residents that if they should come across Jacobs, they should call 911 immediately and not confront him, as he may be armed.
