PLAINWELL, MI -- The Allegan County Sheriff's Office is investigating the death of a Kalamazoo man whose body was found in a car with his two year-old son early Monday morning.

Allegan County Sheriff Frank Baker said that at about 1 a.m. March 6 a motorist flagged down a deputy at a gas station in Plainwell to report that at a nearby store a man appeared to be passed out in a vehicle and that there was a small child in the back seat.

The deputy responded to the location and discovered that the man in the vehicle was not breathing.

The deputy and first responders on scene attempted cardiopulmonary resuscitation of the man, without success.

The dead man was identified as Levi Ryan Newcomb, 29, of Kalamazoo. The 2-year-old boy has been placed with family members.

Additional investigation has determined that there was another man traveling with Newcomb and his child; that man, whose name has not been released, was inside the business, Baker said.

Baker said authorities believe that man may have been inside the store for as long as two hours. Whether he knew Newcomb was dead or not is not yet clear, Baker said, nor do authorities know when and how Newcomb died.

Details about what the other man was doing in the store are not yet being released, Baker said.

The initial investigation indicates that the deceased "has a history of drug abuse, as well as health issues, that may have played part in his death," according to the news release.

This remains an active investigation as detectives have additional follow up investigation to conduct and are awaiting autopsy and toxicology results, Baker said.
