Two members of the group, including its president, were among the passengers of the sunken M/V Trisha Kerstin 3 operated by the Aleson Shipping Lines Incorporated. Zambasulta refers to areas comprising Zamboanga City and the provinces of Basilan, Sulu, and Tawi-Tawi. The ferry reportedly left Zamboanga City on the evening of January 25 bound for Jolo, Sulu, and it sank off Baluk-Baluk Island in Basilan. In 2023, the passenger-cargo M/V Lady Mary Joy 3 of the Aleson Shipping Lines caught fire while traversing the vicinity waters off Baluk-Baluk Island. The family of Zamboanga City Mayor Khymer Adan Olaso’s wife reportedly owns Aleson Shipping Lines.
