From an older article written more than 15 years after Sammy Triumbari's murder in January 1967:
In another conversation with one of his sons, Giacomo Luppino referred to Salvatore Triumbari, a Toronto soft-drink manufacturer whose gangland-style killing in January, 1967, is unsolved. They talked about reports that some of Mr. Triumbari's relatives in Italy were considering trying to kill the man they thought had murdered Mr. Triumbari.

One theory mentioned in the mafia book "ICED" mentions that the orders to have Salvatore Triumbari killed came from Calabria because Salvatore and Filippo Vendemini(another member of the camera di controllo killed in 1969) had some Ndrine member killed and a ritual disfigurement occurred. Michele Racco at the behest of the senior Calabrian leaders acted upon their request. Filippo Vendemini had also worked at CYNAR dry Ltd.Back in the late 60's & early 70's there were a series of fires & bombings at the beverage companies and Italian bakeries owned by prominent Ndrangheta leaders. Also others mafia books Mob rule and Mafia assassin make light of this beverage war. Adding this information to the 1982 article that you mention in your post may give credence to a vendetta theory but it is still too early to tell based on the limited information we have for now.
