The autopsy on Johnson & Johnson heiress Casey Johnson could happen as soon as Tuesday, Los Angeles police said in the wake of the socialite's untimely death at the age of 30.
"Our officers conducted a preliminary investigation,'' LAPD officer Sara Faden said Tuesday. "There was no evidence of any foul play, and the case is now being handled by the coroner's, pending a toxicology report."
Johnson's lifeless body was found Monday afternoon in a West Hollywood home, police said; Faden said Johnson suffered "an apparent natural death."
Johnson was known to indulge heavily in prescription drugs, the source said. The source also said Tila's first reaction after hearing the shocking news of Casey's death was that it was a drug overdose.
The socialite announced her engagement with Tequila just last month; she had previously been involved with Yahoo! heiress Courtenay Semel.
The heiress had many ties to Hollywood, including party circuit colleagues Lindsay Lohan and Paris Hilton, both of whom expressed their grief publicly in the wake of her shocking death.
Her family, headed by New York Jets owner Woody Johnson, issued a statement following her passing: "The Johnson family is mourning its tragic loss and asks for privacy during this very difficult time."
