GREENLAND, N.H. — New Hampshire Attorney General Michael A. “Mike” Delaney has confirmed that one officer was killed and four others wounded during a drug raid on Post Road.

According to multiple reliable sources, the officer killed is Greenland Police Chief Michael Maloney.

Maloney was one week from his scheduled retirement.

Gov. John Lynch was on scene at Portsmouth Regional Hospital, where wounded officers were transported.

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

Two sources told the Herald that Maloney was shot as well as two drug agents who responded to the home of Cullen Mutrie at 517 Post Road.

One of the agents was shot in the chest and the other in the shoulder, according to the sources.

The attorney general is not releasing other names at this time out of respect for family. The attorney general said the next update will be at 6 a.m. at Greenland Town Hall.

Police report the suspect is armed and has a female inside the home with him, but they did not indicate if she was considered to be a hostage.

Police confirmed it was a drug raid operation and that the suspect opened fire on the police officers.

The New England Fire News paging system reported around 8:30 that eight people had been shot, including officers with a high-power rifle.

The police response to the home on Post Road remains ongoing and police have pushed an evacuation zone to a half-mile from the residence, reported to be 517 Post Road. A SWAT team arrived on scene by 7:30 p.m.

Police on scene include at least those from Greenland, Portsmouth, New Castle, Exeter and state police. Police first responded after an emergency call announced an “officer-involved shooting” around 6:30 p.m.

Rye and Greenland ambulances and other emergency apparatus are there as well. Herald reporter Elizabeth Dinan said an ambulance left the scene shortly after 7 p.m. led by a Greenland police escort. Various reports have indicated multiple police officers were shot.

Herald reporter Charles McMahon said a neighbor who lives across the street from 517 Post Road, reportedly the scene of the incident, heard gunshots fired. The neighbor, who is not being named but is known to McMahon, said she saw police officers run from the house and believed it was a drug bust gone awry. Ambulances had arrived on scene shortly after the shots were fired, and the neighbor said she heard additional shots fired.

McMahon said the neighbor with whom he continues to speak said she has been told by police to go down in her basement. The neighbor said she heard multiple gunshots that sounded as if they were from an automatic weapon.

The extent of the evacuation zone is impacting southbound travel along Interstate 95 as police have set up control points along the highway.

A BearCat armored vehicle arrived on scene at 7 p.m. and there are six to eight ambulances.

According to Vision Appraisal, assessing company for the town of Greenland, 517 Post Road is listed the Beverly Mutrie Revocable Trust.

According to a Feb. 2, 2011, Portsmouth Herald story, Cullen Mutrie, age 29, was a resident of the home and had been arrested and charged with possession of anabolic steroids.

According to that story, police alleged liquid and powder steroids were found in Mutrie’s home, when officers went there to confiscate guns after Mutrie’s arrest on charges alleging domestic assault. According to an affidavit by Officer Wayne Young, the steroids were found in Mutrie’s living room coffee table on July 24, 2010, but were not verified as steroids by the state crime lab until Jan. 18.

Emergency communications at 7:15 p.m. reported the suspect as being a very large “juiced” guy, very muscular.
