WINSLOW — A 21-year-old man has been indicted by a Kennebec County grand jury following an attack earlier this year on a man who was stabbed repeatedly.

Justin Boucher of Waterville was indicted last week on one count of aggravated assault and two counts of violating conditions of release, according to court records.

The charges stem from a January incident in which Boucher is accused of stabbing a 65-year-old man in Winslow.

The victim in the stabbing is the focus of a separate investigation by Waterville police on allegations he assaulted someone close to Boucher, and officials said they believe the stabbing was retaliatory.

Boucher was staying with a friend in Winslow when he recognized the older man as the man walked by the morning of Jan. 18. Police said Boucher made a split-second decision to confront the man, and then used a pocket knife to stab him in the back, head, neck and arm.

According to the indictment, Boucher was out on bail on a separate criminal matter and had been ordered not to possess a dangerous weapon and not commit a criminal act.

The alleged violation of those requirements is what prompted the charges of violating conditions of release.

Boucher has pleaded not guilty to the charges stemming from the Jan. 18 incident.
