The families of two New Jersey firefighters who were killed battling a July blaze inside a cargo ship said Friday a malfunctioning vehicle being used to load cargo onto the ship caused the fire. Relatives of Newark firefighters Captains Augusto “Augie” Acabou and Wayne “Bear” Brooks Jr. held a news conference outside the firehouse where the two had worked, saying litigation to be filed in the coming months will seek to hold accountable the Italian shipping company that owned the ship, as well as two stevedore companies involved in loading the vessel. The families already have filed notice of intent to sue the city of Newark, alleging the city did not adequately train firefighters to battle onboard ship fires.
