LOS ANGELES — Kobe Bryant’s widow sued the owner of the helicopter that crashed in fog and killed the former Los Angeles Lakers star and their 13-year-old daughter last month as she publicly mourned their deaths Monday in an emotional public ceremony.

The wrongful death lawsuit filed by Vanessa Bryant in Los Angeles Superior Court said the pilot was careless and negligent by flying in cloudy conditions Jan. 26 and should have aborted the flight that killed all nine people aboard.
