Around 6:45 p.m. Friday, Michigan State Police were called to a domestic dispute situation in Marion Township, Osceola County, MI.

According to witnesses, a man repeatedly ran over an elderly man with his vehicle.

The suspect, 48 year-old Thomas Alger of Marion, killed an 81 year-old man, who police say was a relative of Alger. The victim was pronounced dead at the scene.

Thomas Alger fled the scene in his car heading southbound on M-66. He ran the stop sign at the intersection of M-115, where his car collided with a minivan traveling north on M-115.

Interestingly, one of the 911 callers and first on scene at the crash was Hillsdale City Firefighter Jeffrey Kornak, who was traveling back to Hillsdale from an event in Traverse City when the crash occurred.

He and another woman, a nurse from Flint who was on her way to her cottage, both sprung into action.

Kornak got Alger from his vehicle and performed CPR, but was unable to resuscitate. Thomas Alger was pronounced dead at the scene.

The occupants in the minivan, a woman and two teenage passengers, were badly injured. They were transported to Cadillac Mercy Hospital.

According to MSP, one of the teens was later airlifted to Spectrum Health Butterworth Hospital in Grand Rapids.

The incident remains under investigation by the Michigan State Police.
