CONCORD, N.H. (AP) – An autopsy on Officer Michael Briggs shows that he died from a single gunshot wound to the head and the manner of death is a homicide, the attorney general’s office said Wednesday.

After receiving the autopsy results, the Manchester District Court, at the request of Attorney General Kelly Ayotte, issued an arrest warrant for capital murder against Michael Addison for knowingly causing Briggs’ death. Addison was taken into custody in Boston on Monday.

Briggs, a married father of two, died Tuesday at a Manchester hospital of his wounds. A funeral is planned for Saturday at the stadium that’s home to the New Hampshire Fisher Cats.

Before Briggs died, Addison, 26, of Manchester, was charged with attempted murder.

Meanwhile, three other police officers were at the scene early Monday when Briggs was fatally wounded, a prosecutor said Wednesday.

The names of the others and details such as how many shots were fired and by whom are not being released yet.

, Senior Assistant Attorney General Jeffery Strelzin said.

Authorities said previously that Briggs, 35, and a partner responded on their bicycles to a domestic violence call with a shot fired in Manchester’s inner city and that a third officer was present when Briggs was shot. Strelzin said there were four officers in all – Briggs and his partner, and two officers who drove to the scene.

He also declined to comment on whether Addison, a suspect in a rash of violent crimes during the preceding week, was involved in the domestic dispute.

Two women allegedly involved in the crime spree were arraigned Wednesday in Nashua District Court on charges stemming from the robbery of a Hudson convenience store last week.

According to court records in Manchester and Nashua, Angela Swist, 28, and Teresia Shipley, 26, rode along with Addison and Antoine Bell-Rogers during the robbery and split the money with the men. They also rode along when the men fired shots at a Manchester apartment building early Sunday morning.

Police were responding to a report of domestic violence involving a gunshot when Addison shot Briggs, authorities have said. Police have declined to say whether the dispute involved one of the women.

Bell-Rogers was with Addison during Monday’s shooting, but Addison eluded a massive manhunt until police tracked him to Boston on Monday evening.

In Manchester, people left bouquets of flowers and signed a guest book at the shooting scene and at another makeshift memorial in a yard nearby. An umbrella protected the flowers and lighted candles during a morning rainshower.
