The families of four of the victims who perished in the helicopter crash that killed Kobe Bryant and his daughter, Gianna, have filed wrongful death lawsuits themselves -- this after Vanessa Bryant has already gone after the chopper company in court.
The surviving members of the Altobelli family and Mauser family -- the remaining two Altobelli children and Christina Mauser's husband, her son and 2 daughters, respectively -- claim the Island Express's negligence was reason for the death of their loved ones.
In both suits -- obtained by TMZ -- the surviving family members claim Island Express negligently and carelessly breached its duty to own, lease, manage, maintain, control, entrust, charter and operate the helicopter in question in a reasonable manner.
