LYMAN — A 22-year-old Sanford man, who authorities say was brandishing two knives, died Saturday when he was shot by a sergeant with the York County Sheriff’s Office.

Andrew Landry died at the scene, said Brian MacMaster, chief investigator for the Office of the Maine Attorney General. The AG’s office conducts an investigation whenever a law enforcement officer uses deadly force.

According to MacMaster, deputies were dispatched to 13 Faucher’s Lane, off Huff Road, at about 8:20 p.m. Saturday for a report of an emotionally disturbed individual. When they arrived, they met Landry at the door.

“It quickly turned into a threatening situation with large knives he’d grabbed from the kitchen,” said MacMaster, who estimated the knives were six to eight inches long.

The residence is the home of Landry’s aunt, said York County Sheriff Maurice Ouellette. The woman was in the home with her adult daughter at the time of the incident.

Ouellette said when Sgts. David Chauvette and Kyle Kassa arrived, they managed to usher the aunt and cousin into a bedroom adjacent to the living room.

“They tried to talk him down, but it didn’t work,” said MacMaster.

He said Chauvette fired a stun gun and both probes connected, but the stun gun didn’t work.

“Landry was still advancing,” said MacMaster and was within a few feet of the officers.

That is when Kassa fired his gun.

Ouellette on Sunday said Landry lived in Sanford with his grandmother, but she took him to his aunt’s home on Faucher’s Lane Saturday following an incident in Sanford.

Ouellette declined to elaborate on the nature of that incident and Sanford officers who are authorized to release information to the news media could not be reached today, the Martin Luther King Jr. holiday.

MacMaster acknowledged there was an incident in Sanford earlier Saturday, but said as yet, he didn’t know the specifics.

Sheriff’s deputies had no prior dealings with Landry.

The attorney general’s investigation will examine whether the use of deadly force was justified.

Under Maine law, for any person, including a law enforcement officer, to be justified in using deadly force for self-defense or the defense of others, the attorney general’s office says two requirements must be met. First, the person must reasonably believe that deadly force is imminently threatened against the person or against someone else, and, second, the person must reasonably believe that deadly force is necessary to counter that imminent threat, according to information posted on the attorney general’s website.

MacMaster said he expected the investigation will take up to 60 days to complete.

As well, the sheriff’s office conducts an internal investigation to ascertain policies and procedures were followed, said Ouellette.

In the meantime, Kassa, who has been with the sheriff’s office for a number of years and previously worked with Buxton Police, is on paid administrative leave, a standard procedure. He was promoted to sergeant in 2010.
