"I ask the people of New Hampshire to join me in honoring the sacrifice of Chief Maloney, and supporting his family at this time. Our deepest condolences also go out to the Greenland Police Department and the entire community.

We are also praying for the recovery of Officers Eric Kulberg of the University of New Hampshire Police Department, Scott Kukesh of Newmarket, Greg Turner of Dover and Jeremiah Murphy of Rochester, who were wounded during this incident."

UPDATE, 12:40 A.M.: The New Hampshire Attorney General's Office has released the names of the other officers wounded in Thursday's incident in Greenland, according to multiple reports.

Detective Scott Kukesh, of the Newmarket Police Department, and Detective Jeremiah Murphy, of the Rochester Police Department, were both shot in the chest and were in intensive care.

Detective Gregory Turner, of the Dover Police Department, and Detective Eric Kulberg, a Winnacunnet High School graduate and a member of the University of New Hampshire Police Department, were both treated for their gunshot-related injuries and released from the hospital, according to multiple reports.

UPDATE, 10:15 P.M.: Greenland Police Chief Michael Maloney has died of gunshot wounds sustained in tonight's incident in Greenland, Selectmen Chairman John Penacho confirmed tonight.

"We're stunned," Penacho said. "It was a blow to all of us."

Maloney, 48, headed a small police department of seven officers, including himself. Penacho said he wasn't surprised that Maloney, who had once also served in the North Hampton Police Department, went out on tonight's drug investigation.

"He was a working police chief," he said. "(He did) traffic stops, or whatever was needed."

Penacho said Maloney was married and had several children.

UPDATE, 10 P.M.: Attorney General Michael Delaney confirmed at a press conference minutes ago that five police officers were shot tonight in Greenland, and one of them has died.

Delaney, in a press conference at Greenland Town Hall, said law enforcement responded to 517 Post Road around 6 p.m. and were conducting a drug investigation. They entered the home and encountered an armed subject who shot rounds at them.

He said there was no more information he could provide, because authorities are still dealing with "an active armed standoff at a home." A man and a woman are reportedly barricaded inside the home at this hour.

"I do want to extend my thoughts and prayers to the family and relatives and loved ones of the police officer who has been killed and the four police officers who have been injured," Delaney said.

He said the names of the officers who were shot are not being released pending notification of relatives and loved ones.

Delaney would not answer specific questions about the investigation, but said another update will be provided at 6 a.m. Friday.

Deputy House Speaker Pam Tucker, who represents Greenland, said her town is in shock.

"We're just trying to stay together," she said. "As you know, it's still an active standoff, so we're all hanging tough."

An earlier story follows:

Multiple police officers were reportedly shot early this evening as law enforcement agencies have surrounded a house in Greenland.

WMUR is now reporting that one of the officers shot was Greenland Police Chief Michael Maloney, who was set to retire later this month. His condition is not known at this time. A law enforcement source said four other officers were also shot, two of whom are now in critical condition.

The incident was first reported around 6:50 p.m. at 517 Post Road. The officers were reportedly at the home to serve a search warrant. Initial reports were that anywhere from two to five police officers had been shot, and that a male suspect had barricaded himself inside the home with a high-powered rifle.

It isn't clear if anyone other than the police officers might have been shot, although one witness at the scene said they saw a woman who was not a police officer who had been shot.

According to Greenland assessment records, the home at 517 Post Road is owned by the Beverly P. Mutrie Trust. The 1-1/2 story building is valued at $280,000.

A man listed as living at that address, Cullen Mutrie, 29, was charged last year with nine felony counts alleging he was in possession of anabolic steroids, according to Seacoastonline. The website also reported that Mutrie had previously been barred from possessing firearms after he was arrested for assaulting a woman. Mutrie is a former Hampton Falls firefighter, the Union Leader is reporting.

Stratham resident Susan Whitter was in the area as the police cruisers began flying to the scene.

"Police officers from Newmarket, Exeter, Stratham, Newfields. They were just calling them in left and right," Whitter said. "Just a barrage of activity. I mean flying to the scene and I came out here and saw this. Just utterly amazing in a small town like this."

SWAT teams and police from Exeter, Hampton, Portsmouth and other area departments are all at the scene. All officers are reportedly down behind cover.

Post Road has been closed to vehicle traffic between Winnicut Road and Portsmouth Avenue.

A helicopter is flying overhead, and the area near the house is evacuated, save for a home across the street, but the person in that residence is safe and secure, according to police.

That person apparently witnessed the shooting, bystanders are saying.

Tyler Bryant, 18, of Portsmouth, said a friend of his was on his way home and saw the whole incident happen. His friend was Tweeting details about the incident before police escorted him from his house, which is located near the scene.

Gov. John Lynch issued a statement about the shooting incident, saying he has been monitoring the situation from the Emergency Operations Center in Concord, keeping in close contact with law enforcement officials. The governor is reportedly on his way to Portsmouth Regional Hospital, where the wounded officers were taken.

"This is a tragic incident, and my thoughts and prayers are with the officers involved and their families," Lynch said.

U.S. Sen. Jeanne Shaheen also issued a statement, saying, "All of our thoughts and prayers are with the families and loved ones of the officer killed and with the officers wounded, their families, and everyone affected by this terrible tragedy."

Seacoast Online reported that Maloney's retirement was accepted by the Greenland Board of Selectmen March 26. They reported Maloney originally joined the department in 2000 and spent 26 years in law enforcement before his retirement. Maloney's last day on the job had been scheduled for April 20.
