Family members of four of the eight passengers killed in a helicopter crash with Kobe Bryant and his daughter have joined the NBA star’s widow in filing wrongful death lawsuits against the companies that owned and operated the aircraft. The suits on behalf of three members of one family, and a woman who helped coach Bryant’s 13-year-old daughter in basketball, were filed electronically Sunday in Los Angeles Superior Court. The pair of lawsuits comes about two months after Bryant’s widow, Vanessa, the mother of Gianna, also sued Island Express Helicopters Inc., which operated the Sikorsky, and its owner, Island Express Holding Corp.
