The man convicted of killing his girlfriend and putting her in a septic tank was supposed to learn his sentence on Friday, but that has been delayed. Collin Boucher-Gionet pleaded guilty to manslaughter and indignity to a body in May. Aylissa Rovere, 32, was reported missing in the fall of 2024. Her body was discovered on a rural property north of Stony Plain. According to the agreed statement of facts, Boucher-Gionet woke up after blacking out from intoxication to find Rovere motionless and cold and believed she was dead. The court documents say he began to dig a grave for her on the property and also prepared to burn her body. He later dumped it into a nearby septic tank. An autopsy found Rovere was alive at the time she was dumped in the tank and died of drowning. On Friday court heard victim impact statements from Rovere’s family, including her two children. The Crown asked for a 12-year sentence, while the defence raised concerns, which resulted in proceedings being adjourned. Boucher-Gionet will be back in court next month where an application to strike his guilty pleas could be made or both sides could present a joint submission.
