Around 12:30 p.m., police received a 911 call for a domestic attack on the Rite Aid car park on Mammoth Road in Manchester.
Police found an injured woman driving away from a Toyota RAV4. A gunman was still in the vehicle and refused to leave, police said.
A clash ensued and shortly after 2 a.m., police shot and killed 33-year-old Adnan Huseynovich of Manchester.
No one else was injured during the incident.
Attorney General John Formella said the initial investigation showed that four Manchester police officers fired their weapons during the incident. Two New Hampshire State Police soldiers also fired their weapons.
The first officers to respond wore body cameras. Formella said investigators would look into whether the cameras, along with cruise cameras, recorded the incident.
