A man is dead and another is in critical condition following a shooting in Seabrook, New Hampshire, on Monday morning.
The man believed to have shot the other two has been identified, but no one is in custody or facing charges, state prosecutors said at a news conference Monday afternoon. There was believed to be no ongoing danger to the public.
"The three of them knew each other. The full nature of the relationship is something that we're exploring at this time," Senior Assistant Attorney General Ben Agati said.
None of the three men, all middle-aged, have yet been identified.
The New Hampshire Attorney General's Office said Seabrook police were first alerted to the incident by a 911 call shortly after 9 a.m. reporting a shooting on Boynton Lane.
When police arrived, the attorney general's office said they found a man dead in the driveway outside the home, and a second man suffering from a gunshot wound. The second man was taken to an area hospital and is in critical condition.
A third person was reported to have fled the scene, but no one was arrested, charged or in law enforcement custody, officials said. A weapon believed to have been involved in the shooting has been located.
Agati didn't know what sparked the shooting: "The real nature of the relationship between those people, we're just starting to drill down into what that is."
Earlier, Hampton police had said that an arrest had been made after a 90-minute long manhunt that prompted a heavy police and SWAT response on Route 1 in the area of several businesses, including a Market Basket and a Walmart.
The arrest eliminated the public threat, Hampton police said. Officials continued to urge people to avoid the area, however.
Aerial footage showed numerous police cruisers, SWAT and tactical vehicles surrounding a residential area that bordered several businesses.
"This is believed to be a contained scenario, and all parties are believed to have been identified to this shooting," the attorney general's office said in a statement. "Currently, officers are completing a search of the area outside the home and will be on Boynton Lane for several hours."
Christian O'Brien lives nearby and heard the gunshots. He stayed inside, afraid to go out, until about half an hour later, after police and ambulances had shown up. He said police were at the house where the shooting took place before and there have been issues.
"We've had a lot of altercations with just living behind these guys and it's been a battle back and forth," he said.
Allison L'Heureaux was shopping at a nearby Market Basket when she heard an announcement ordering everyone to shelter in place. People inside were ushered into the storeroom.
"When I heard 'shooter,' I didn't know if the person was in the store, I didn't know if I should be hiding. I didn't know what to do," she said.
