NASHUA - The man found dead in his Dane Street home early Thursday morning following a lengthy stand-off with police has been identified as Michael Conway, who died from an apparent self-inflicted gunshot.

Conway was in his yard when police arrived at 2 Dane St. early Wednesday evening to arrest him on robbery charges, but Conway retreated into his home.

According to authorities, Conway, 56, had allegedly robbed a store clerk at the HRA Market, 590 S. Main St., about 8 p.m. on Tuesday. Conway, a regular customer at the store, allegedly demanded money as he pointed a handgun at the clerk and threatened to shoot him before the worker handed over an unspecified amount of cash, said police.

Using video surveillance, authorities were able to identify the vehicle involved, which eventually led police to Conway.

Police, attempting to issue the arrest warrant, returned to Conway’s home Wednesday evening, this time with the Nashua Police Special Reaction Team and the Hostage Negotiation Unit, according to a press release.

Several nearby residents were evacuated while Conway barricaded himself inside his residence, still considered armed and dangerous.

Police began initial communications with Conway via telephone, but he eventually ended the calls and refused to exit his residence after police made several pleas using a bullhorn. Following a six-hour standoff, a robot was sent into the home, which located Conway’s body around 1:50 a.m.

A deputy medical examiner from the state assisted with the investigation and ruled the death a suicide, apparently from a self-inflicted gunshot, according to a press release.

During a search of the home, physical evidence in connection with the robbery at HRA Market was located, said police.

Neighbors were shocked about the heavy police presence in the small neighborhood just off East Dunstable Road.

Eric White, who lives nearby at 21 East Dunstable Road, told the Union Leader that Conway is "actually a super nice guy," and lived alone at the residence. Police initially told White and his wife to go to their cellar as a safety precaution on Wednesday evening, early on during the standoff.

A resident who lives on Dane Street said Thursday morning that the neighborhood is typically quiet. The man, who declined to give his name, said he was stunned to learn about the suicide.

"It seems like it was a bad situation altogether," said the neighbor, who was unsure how long Conway resided at the small brown house at the corner of Dane Street and East Dunstable Road.
