80-year-old man critically injured after being hit by ATV

The victim was taken to a hospital to be treated for serious injuries and was in critical condition as of Tuesday, police said.

Suspect 'wanted to confess a crime involving an ATV driver'

On Monday, police said they were contacted by a man who said he wanted to "confess a crime involving an ATV driver within the last 24 hours." The man told police to "send someone to pick me up." 

Arriving officers, assisted by Houghton County Sheriff's Office deputies responded to the man's home in Quincy Township, about 2 miles east of where the elderly man was run down. There, the sheriff's office reported, they found a 22-year-old man dead from what appeared to be a single self-inflicted gunshot wound. 

Police obtained a search warrant for the home, where deputies recovered several electronic devices and the ATV reportedly used in the crime and the clothing the suspect wore during the incident.

An autopsy is expected to reveal the man's official cause and manner of death.

The victim's updated condition was not immediately known.
