A Mississippi murder suspect used a detective's gun to kill the detective and then himself inside police headquarters.

Mississippi Bureau of Investigation spokesman Warren Strain said Friday that 23-year-old Jeremy Powell overpowered Jackson Police Detective Eric Smith, took his service weapon and shot Smith. Powell then shot himself.

Officials are slowly releasing details of how the men died Thursday. The state agency took over the investigation from the Jackson Police Department.

Powell was being questioned in connection with the stabbing death earlier this week of a 20-year-old Jackson man.

Autopsies were to be performed Friday.

Officials continue to mourn the death of Smith, a 40-year-old detective who investigated a number of high-profile murder cases in Mississippi's largest city.
