According to police, at least three people were killed when a gunman opened fire at Michigan State University.
Police said the suspect died from a “self-inflicted gunshot wound” in addition to the three victims.
Another five people were injured in the late-night attack on East Lansing’s main campus.
The suspect was described as “a black male of shorter stature” by police. They later revealed that he was 43 years old and had no known ties to the university.
Students and local residents were told to shelter-in-place during the manhunt, however police later lifted the order, saying there was “no longer a threat to campus”.
The suspect was “located off campus,” they added.
The suspect was wearing a denim jacket, a navy baseball cap, and red sneakers in earlier photos.
On Monday, shortly after 20:00 local time, the shooting began (01:00 GMT Tuesday).
Officers responded to the attack and discovered victims at Berkey Hall on the north side of campus and the adjacent Michigan State University Union building.
The police said at a press conference that there were several crime scenes and that their investigation was ongoing. The attacker’s motivation is unknown.
A number of ambulances were seen arriving on the scene, and the injured, some of whom are believed to be in critical condition, are now being treated in hospital.
“We are truly living a nightmare tonight,” said Deputy Chief Chris Rozman of the university’s police force.
For at least 48 hours, all campus activities have been canceled. East Lansing is located approximately 70 miles (112 kilometers) north of Detroit.
