3 students were killed at Michigan State University

The victims were all students at the university, police said, and the injured remain in critical condition.
The police said a caller's tip led them to the suspected gunman, who died from a self-inflicted gunshot wound.
The suspect, who has since been identified, had no ties to MSU.
"We can confirm that the 43-year-old suspect had no affiliation to the university. He was not a student, faculty, or staff, current or previous," Chris Rozman of the Michigan State University Police said.
