The New Hampshire attorney general's office says a man who barricaded himself in a Claremont building died during an exchange of gunfire with half a dozen state police officers.
A police SWAT team was called late Wednesday to a building described in real estate listings as an industrial warehouse property.
Local police in Claremont had responded to the area earlier for a report of gunshots fired.
Authorities said Thursday that 40-year-old Jeffrey Ely died of multiple gunshot wounds to the head, neck, arms, legs and torso.
The troopers, whose names have not been released, did not have body or cruiser cameras.
