Los Angeles County coroner spokesman Craig Harvey says examiners on Tuesday deferred the cause of death for the daughter of New York Jets owner Woody Johnson.
Casey Johnson was found dead Monday in her Los Angeles home. Harvey says examiners found no evidence of trauma on the 30-year-old's body and are also considering her medical history and her diabetes.
Harvey says results of toxicology and other tests could take six weeks or more.
Tabloids documented Johnson's exploits with friends such as Paris Hilton and Tinseltown's other privileged party girls.
