FORT DRUM — Army officials said Staff Sgt. Dustin J. McMillen, who was killed by on-post police during a standoff early Saturday, had not sought or been referred for counseling for a battle-related illness or post-traumatic stress disorder.

"This has been a terrible tragedy for everyone concerned and our primary concern right now is to take care of the physical and emotional needs of his family as well as those of the officers involved in yesterday's shooting," public affairs officer Lt. Col. Paul Swiergosz said during a press conference Sunday.

According to Col. Swiergosz, the incident began with a hang-up call to 911 from Sgt. McMillen's home, 9934B Saratoga Road, at 1:30 a.m. Saturday. He said when the two investigating officers arrived, Sgt. McMillen told them the call was a misunderstanding.

However, as the officers collected their information Sgt. McMillen drew a concealed handgun and ordered the officers to surrender their weapons.

A second patrol responding entered the home and found Sgt. McMillen holding the first two officers at gunpoint. After the second patrol attempted to have Sgt. McMillen surrender to them, the soldier fired two shots in the general direction of the second group of officers. At that point one of those in the second patrol fired two shots at Sgt. McMillen, both of which struck him.

The police reported that Sgt. McMillen was alive when he was captured. He was taken to Samaritan Medical Center, Watertown, where he was pronounced dead.

According to Col. Swiergosz, preliminary results from an autopsy performed Saturday were consistent with the sequence of events presented by the police.

Col. Swiergosz declined to name any of the officers involved in the incident as they were still being debriefed. He said the gun Sgt. McMillen used was not military issue and officials do not yet know if it was registered in the state.

Sgt. McMillen's family, a wife and three children, have been moved to temporary housing on-post and have been receiving counseling from a chaplain.

Col. Swiergosz said those who knew Sgt. McMillen described him as a "good soldier" and warned against jumping to judgment.

"I believe it would be a mistake for anyone to define this man's life by one tragic action," he said.

Fort Drum's Criminal Investigation Division is continuing its inquiry into the incident.
