Michigan State University shooter dead after killing 3, injuring 5 others
Police confirm that the Michigan State University shooter shot himself hours after shooting eight people on the East Lansing campus. He killed three people and injured five others before an hours-long manhunt that ended off campus.
According to police, the suspect was a 43-year-old man who did not have a connection to the school, further complicating the investigation into the motive. The buildings where the shootings happened are open to the public.
"We have no idea why he came to campus tonight to do this," said MSU Deputy Chief Chris Rozman.
Police would not confirm if the victims were students at MSU.
