A third person from Quebec has been charged in connection with a home invasion in South Glengarry that left two people dead in February 2025.
Marc André DeMontigny-Defoy, 36, of Coteau-du-Lac, Que., was to appear in court at Cornwall on Wednesday to face charges stemming from the incident at a residence on Old Highway 2 on the evening of Feb. 2, 2025.
The charges against DeMontigny-Defoy include: conspiracy to commit an indictable offence; break and enter of a dwelling house with intent to commit an indictable offence; possession of a weapon for a dangerous purpose; break and enter with intent to steal a firearm; committing a robbery to steal a firearm; unauthorized possession of a firearm; knowledge of unauthorized possession of a firearm; armed robbery; and possession of a firearm or ammunition contrary to a prohibition order.
Two people in the South Glengarry residence with gunshot wounds were pronounced deceased, while a third individual fled the scene before police arrived, the Ontario Provincial Police said in a news release dated Oct. 21, adding that the residents of the home were uninjured.
The victims were later identified as Eddie Alobhouet, 19, and Tristan Simard, 18, both of St-Jérôme.
Police believed it was a targeted incident, the release said.
In August 2026, the OPP charged two other Quebec residents in the case.
Michael Cloutier, 40, of Valleyfield, was charged with: conspiracy to commit an indictable offence; break and enter of a dwelling house with intent to commit an indictable offence; disguise with intent; possession of a weapon for a dangerous purpose; break and enter with intent to steal a firearm; committing a robbery to steal a firearm; unauthorized possession of a firearm; knowledge of unauthorized possession of a firearm; armed robbery; and possession of a firearm or ammunition contrary to a prohibition order.
Cloutier remained in custody and was scheduled to appear in court in Cornwall on Oct. 27.
Also charged was Stephanie Pigeon, 34, of St-Jérôme: accessory after the fact to commit an indictable offence and obstructing justice.
Pigeon was released from custody following a bail hearing and was scheduled to appear in court at Cornwall on Nov. 17.
The investigation remains ongoing, led by the Stormont, Dundas and Glengarry detachment, the OPOP said.
