A man died in his yard Wednesday, and Prince George’s County fire officials said he may have been electrocuted.

About 5:45 p.m., rescue crews were called to the 7700 block of Oxman Road in the Palmer Park area on a report of an unconscious man in his yard, said Mark Brady, a fire department spokesman.

The man, who was identified only as being in his 30s, was found with electrical wires on or around his body. Authorities pronounced him dead at the scene, Brady said.

The man’s injuries appeared consistent with electrocution, but officials said an autopsy would be performed at the state medical examiner’s office to determine the cause of death. Officials said it appeared that the man had suffered the injuries earlier in the day.

It was unclear whether the wires were utility wires or outdoor home-improvement equipment, Brady said. Officials called Baltimore Gas and Electric workers to secure the site.

County police officials said the matter is being investigated but declined to give details about the incident.
