A 16-year-old boy pleaded guilty Friday to the execution-style killing of a rival gang member two years ago in the city's North End.
The boy, who was 14 at the time, shot David Michael Vincett, 20, in the back of the head with a .357 Magnum revolver in the early morning of Sept. 25, 2011.
The boy will be sentenced as an adult Sept. 9.
At a preliminary hearing in January, court was told the boy was arrested after his younger brother told school officials his brother had committed the killing.
Crown counsel Lisa Carson said when arrested by police, the boy admitted to the killing, saying it was in revenge for the stabbing death of a fellow Indian Posse member a couple of weeks earlier.
Carson said the boy had bought the .357 Magnum and 20 rounds of ammunition following the killing of his friend, Clark Stevenson, who was 15, vowing revenge on the rival MOB gang, believed responsible for the death.
The boy went to a friend's house in the 500 block of Boyd Avenue in the early hours of Sept. 25, 2011, where he showed them the revolver and made his vow to kill an MOB gang member.
Just at that time, Vincett was walking down Boyd wearing MOB colours -- a bandana and neck scarf. The boy ran after Vincett and confronted him, calling out to him: "IP."
Carson said the boy told police that Vincett replied: "MOB... P-K," which in street lingo means Posse Killer, that he was a member of the MOB and he had killed an IP gang member.
The boy told police he pulled out his handgun and Vincett fled.
Carson said the boy dropped to one knee, held the handgun with both hands and fired a single shot at Vincett, hitting him in the back of the head, killing him instantly. A passerby found his body and contacted 911.
The boy ran to his home on Aberdeen Avenue, where he told his mother, two sisters and brother what he had done. One of his sisters took the handgun and bullets and hid them at her house and his mother told her other son to throw out his brother's clothes.
Vincett's mother told the Free Press her son was not in a gang but wore gang colours believing they would provide him protection from other gangs.
The boy's defence counsel has not objected to a Crown motion to have him sentenced as an adult, which will see him serve between five to seven years before he is eligible for parole.
