Six people on board died as a result of the crash, including the former Navy SEAL pilot Seankese Johnson, Agustin Escobar, his wife, Merce Camprubi Montal, and their three children, aged 4, 5, and 11. According to Democratic Jersey City Mayor Steven Fulop, Escobar was in town for a business trip the family extended to celebrate Montal’s 40th birthday.
