Andrea Gross, the mother of the late Adam Goldstein (DJ AM), is alleging that her son’s death was the result of the plane crash that he survived in September 2008, People reports. In a $20 million lawsuit against the plane manufacturer Learjet and the pilots’ estates, Gross has added a wrongful death claim. “The crash ultimately caused Goldstein’s death at a later date,” the lawsuit alleges. Goldstein died in August of an accidental drug overdose. A trial is currently set for March 2.
