LEWISTON, Maine — A Maine State Police detective who was shot and killed in the line of duty is being remembered Tuesday on the 20th anniversary of the shooting.

Giles Landry was gunned down in his cruiser outside a mobile home in Leeds on March 31, 1989, while investigating a child abuse case. A woman he had been talking to was fatally shot in the passenger seat, and the gunman — 36-year-old David Grover — then took his own life.

Landry was the last Maine police officer to die by gunfire. He was 36.

Maine State Police radios went silent for a minute on Tuesday morning to pay tribute to Landry.
