LOS ANGELES—The autopsy of Johnson & Johnson heiress Casey Johnson is inconclusive and toxicology tests have been ordered.
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.
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. She recently got engaged to bisexual reality TV star Tila Tequila.
