Socialite Casey Johnson lay dead for days before her body was discovered at her home in Los Angeles on Monday morning (04Jan10), according to police sources.
The Johnson & Johnson heiress, who was reportedly engaged to reality TV star Tila Tequila, had a history of diabetes and twice slipped into diabetic comas, according to TMZ.com.
Officials have completed an autopsy on the 30 year old's body and determined there were no signs of trauma on Johnson's body.
Law enforcement sources claim she had been dead for several days.
The cause of death is deferred pending toxicology tests.
Tequila has revealed she last saw her fiancee on 28 December (09), when the couple fought.
The reality TV star tried to contact her partner by phone over the New Year weekend, but could not get hold of her.
