the only full patch HA member that i have reference to controlling salaberry-de-valleyfield is david lefebvre. he was best man to martin robert at his 2018 wedding. as for whom dumont is associated with from HA i cant say its lefebvre nor does the article. dumont then could be an associate of an associate to a full patch member. i would think attacks like these as is common go through a series of 'buffers'.
