The family members of four passengers that died in the same helicopter crash that killed Kobe Bryant and his daughter  have sued the the helicopter company involved.

Evening Standard reports that the family members of four passengers killed in a helicopter crash have joined the NBA star’s widow in filing wrongful death lawsuits against the owners and operators of the aircraft.

The pair of lawsuits comes two months after Mr Bryant’s widow, Vanessa, the mother of 13-year-old Gianna, also sued Island Express Helicopters Inc, which operated the helicopter, and its owner Island Express Holding Corp.

The new identical seven-page cases do not name the dead pilot, Ara Zobayan, or his representative, as a defendant unlike Vanessa Bryant’s lengthy lawsuit.

One the suits, one  was filed by two children of Orange Coast College baseball coach John Altobelli, his wife, Keri, and their daughter Alyssa, who played basketball with Gianna.

They did not give it a halt as another suit was filed by the husband and three children of Christina Mauser, who helped Mr Bryant coach the girls’ basketball team.

The two families allege that the two companies were careless and negligent.
