LOS ANGELES, California (X17online) - The wife of Travis Barker's assistant is suing several aviation companies and the estates of two pilots over the crash that killed her husband earlier this year in South Carolina.

Otilia Villar Baker, wife of Chris Baker, filed the suit in Los Angeles Superior court, alleging negligence and wrongful death. The lawsuit was also filed on behalf of the Bakers' young son, Sebastian.

The suit claims the companies contributed to the Sept. 19 crash that also killed the two pilots and Barker's bodyguard. Barker and Adam Goldstein, known as DJ AM, were severely injured.

The suit seeks damages for pain and anguish Barker's long-time assistant suffered before his death, loss of earnings, companionship, repayment of funeral and other costs.

Travis Barker sued the same companies, which include Clay Lacy Aviation, Goodyear Tire and Rubber, Bombardier Inc., Global Exec Aviation and Inter Travel & Services, last month.
