GREENLAND — The man believed to be the shooter who killed Greenland Police Chief Michael Maloney and shot four other officers was found dead inside his Post Road home around 2 a.m. Friday along with a female aquaintance, Attorney General Michael Delaney said at a 5 a.m. news conference.

The gunman was identified as Cullen Mutrie, 29, a resident of the home at 517 Post Road where the shooting occurred.

Delaney said authorities are investigating whether Mutrie and the woman, whose identity isn't known, died of gunshot wounds as a result of a double suicide or a murder-suicide.

The two were found dead around 2 a.m. when a tactical team sent a robot into the home. The decision to send the robot in came after police negotiators lost contact with Mutrie for a long period of time, Delaney said.

“The tactical team was able to have brief contact with Mutrie, but that conversation ended shortly thereafter,” Delaney said.

Law enforcement sources said police showed up at the Post Road home to serve a search warrant about 6 p.m., and discovered that a drug deal may have been taking place.

Mutrie was indicted on charges of possession of a controlled drug last May for having a variety of anabolic steroids, court documents show.
