Did the city rehire worker after killing colleague?

 Here's one that sits in the awful intersection of stupidity and tragedy: In July 1995 a veteran City of Montreal worker named Michel Dubois, aged 40, decided to prank colleague named Joseph Villa, 38, so he sped at him with his city vehicle with the aim of stopping just before impact.
    But Dubois' stupid idea of a stunt screwed up when he failed to stop in time and ended up pinning the guy to the water truck, killing him in the parking lof of the Miron quarry.
   For the record, Villa was actually doing something useful while Dubois was acting like an idiot. He was busy closing the valve on a water truck.
   Dubois then apologized as the guy lay dying and then drove off. He surrendered to police later that day.
    Dubois had been secretly driving without a license. He had his license taken away a year prior due to drunk driving.
    The city suspended and fired Dubois for leaving the scene, leaving prior to the end of his shift and not telling his employers that his license had been revoked.
   Dubois had previously worked as a security guard in two city zoos and was caught selling exotic animals to pet shops to pay off debts and support a drug habit. He sold a parrot, two budgies, two boas and a crow. He also smoked a morphine-based drug that the zoos employed to put animals to sleep.
   He avoided dismissal by signing onto a detox program.
   After killing his colleague, Dubois pleaded guilty and his lawyer asked for six month sentence. Prosecutors asked for 24 months. A judge sentenced him to 18 months. He said he had a nine-month-old child - who'd be about 30 now - and a girlfriend for the past two years.
  The city fired Dubois but the blue collar union sought to have him reinstated and requested he be paid in full retroactively. It is unknown whether he got his job back or not, but I'd be curious to know.
