(CNN) —  

A murder suspect in Jackson, Mississippi, overpowered a detective and shot him with the detective’s gun before killing himself, Mississippi Bureau of Investigation spokesman Warren Strain said Friday.

Veteran detective Eric Smith, 40, was talking with suspect Jeremy Powell, 23, when other officers heard the shots and rushed into the interview room at the police station, said Chris Mims, a spokesman for Jackson Mayor Harvey Johnson.

Both men were dead. Autopsies were performed Friday morning.

Jackson, a city of about 175,000 residents, is the capital of Mississippi.
