Dauphin County District Attorney Ed Marsico said Wednesday that the gun issued to Harrisburg Officer William Owens discharged and struck the officer's wife.
Marsico said he believes the shooting was an accident but charges could be filed if an investigation determines Owens acted recklessly.
Owens' wife was treated at a hospital after the incident Saturday evening.
A city spokesman said the officer has been suspended without pay pending the outcome of an investigation.
