Authorities have ruled that the death of a Barnesville man found trapped under a garage door was an accident.

Preliminary autopsy results find that 51-year-old Steve Peterson died of asphyxiation.

Barnesville Police Chief Dean Ernst told the Forum newspaper that Peterson apparently was unable to breathe when the garage door came down on his chest.

Peterson, a part-owner of Barnesville Bus Co., was found March 7 at the business.

The police chief has said Peterson apparently was trying to duck under the garage door as it was closing when he somehow got caught under it.
