He spent an hour walking outside within the area, crossing Grand River Avenue and passing the Broad Art Museum before the first shots fired call was received by Ingham County 911 at 8:18 p.m.

Officers arrived at the scene two minutes later and police believe the shooter fired one shot while walking from Berkey Hall to the Union shortly after.

The shooter entered the Union at 8:24 p.m., with the first shooting report from the building coming two minutes later. He then exited the building and left campus. Shortly after this, MSU's first shelter-in-place alert was sent.

The shooter then proceeded to walk a near five-mile route toward Lake Lansing Road and Larch Street.

He walked on Grand River Avenue, before turning onto Harrison Road. It is here that police say he was spotted walking northbound around 9:14 p.m. An alert was sent out notifying the campus and the city at 10:04 p.m.

On Lake Lansing Road, police are notified of someone matching the shooter's description at 11:35 p.m.

At 11:50 p.m., after turning onto Larch Street, the shooter was approached by police and proceeded to shoot himself fatally.

Around 40 minutes later, the shelter-in-place was lifted.
