Michigan State University Police interim Deputy Chief Chris Rozman said during a news conference Tuesday morning that McRae had no affiliation with the university.

"He was not a student, faculty, staff, current or previous," he said.

Rozman added that McRae was found -- dead of a self-inflicted gunshot wound -- after a tip.

Police received multiple 911 calls about a shooting near the university's social science building, Berkey Hall, on the East Lansing campus at 8:18 p.m. Monday and a second shooting at the nearby MSU Union.

Authorities have not discovered a motive for the shootings.

"We have no idea why he came to campus tonight," Rozman said.

Authorities also said that they had found a note in McRae's pocket that made threats to two public schools in Ewing, N.J. The Ewing Police Department said that McRae had ties to the area, and out of an abundance of caution, Ewing Public Schools were closed for the day.
