Authorities say the man who killed a detective at police headquarters in Mississippi's capital city shot himself twice in the head after shooting the officer.
Hinds County Coroner Sharon Grisham-Stewart said Tuesday that Jeremy Powell shot himself twice in the head after killing veteran Jackson Police Det. Eric Smith on Thursday.
Grisham-Stewart had said last week that the 23-year-old Powell had died from a self-inflicted gunshot wound to the head.
She said Tuesday that it may seem unlikely, but it's possible for a person to shoot himself twice in the head.
Authorities say Powell was being questioned about a stabbing death when he grabbed Smith's gun during an interview on the third floor of the department.
Grisham-Stewart says the 40-year-old Smith was shot four times.
