The house where a Brentwood, N.H., man killed a police officer last week exploded because some of the bullets the man fired pierced gas pipes in the basement, and the gas released later came in contact with multiple fires he had set, authorities said today.
Authorities released more details of the harrowing situation faced last Monday afternoon by Officer Steven Arkell, 48, who was killed when he responded to a domestic abuse incident and came under fire from Michael Nolan, 47.
But mystery still surrounded key questions, including Nolan’s alleged motive for attacking the officer.
New Hampshire State Police Sergeant Joe Ebert said the one person who might be able to shed light on what led up to the fatal confrontation was unable to: 86-year-old Walter Nolan, who had been in a pitched verbal dispute dispute with Michael Nolan and had let Arkell into the home, moments before Michael Nolan began firing.
Declining to comment on Walter Nolan’s mental condition, Ebert said Nolan would know the answers to what went on before Arkell had arrived, but “we are unable to recover those answers.”
