In the late evening of May 1st, Douglas Lewis was killed after he was shot four times by Watertown resident Anthony Trifiletti after a minor traffic accident.

Trifiletti, who was licensed to carry a firearm, told authorities that he shot Lewis — who was unarmed — because he feared for his life.

Lewis pulled over and Trifiletti pulled over behind him and when Lewis got out of his car, presumably to ask why the 25-year old was following him, the shooter claimed he saw Lewis reaching under his shirt.

Valerie Lewis said a witness to the shooting told her that Trifiletti took a shooter’s stance, aimed, and fired his weapon, “like he was a professional.”

However, the killer has had contacts with police including a DWI and he was involved in a traffic accident that caused the death of another motorist about a year ago.The mother of the accident victim, Karen Malave, was in court showing support for the Lewis family.
