Barbara Norton-Homer, 29, and her friends Katy McComber, 19 and Sherry Delisle, 21 were drunk and high and angry and left the Kahanawake reservation to start trouble on October 23, 1979
They stopped a taxi driven by Fernand Giroux, 49, in LaSalle and beat him bad enough to take out an eye and leave him paralyzed, but his suffering didn't last long, as he died in hospital from his wounds two weeks later.
The three then spent a couple of hours aimlessly driving around LaSalle and over the Mercier Bridge in the taxi they had stolen from him.
Cops eventually spotted them and followed them to Khanawake, where they drove after them down a dirt road.
It was apparently a trap, as the women were trying to lure cops to the reserve.
When they finally pulled the girls over, another car appeared and its occupants threatened the police with guns.
Soon after, official Khanawake peacekeepers arrived on the scene and took charge of the situation, holding the girls in captivity until handing them over to Montreal police a couple of days later.
It seems that the three were angry that a Kahnawake native named David Cross had been shot dead a couple of days earlier after smashing a police cruiser with a pool cue following a high-speed chase.
The death inspired the fatal attack on the blameless cabbie. The provincial police officer Robert Lessard was charged with manslaughter but was acquitted in November 1980.
Norton, who had a history of mental illness, was seen as the ringleader and was sentenced to seven years in prison, while McComber got six and Delisle got four years, all for manslaughter.
Fellow cabbies held a small parade for their slain colleague.
