Lisa Robin Kelly - Lisa Robin Kelly Cause Of Death Remains Unknown
Tragic actress Lisa Robin Kelly's passing remains a mystery after her autopsy failed to uncover a cause of death.
The That '70s Show star passed away aged 43 on Wednesday (14Aug13) at a rehabilitation facility in California, just two days after she admitted herself to the clinic in a bid to tackle her long-running alcoholism.
It was believed the star suffered a fatal cardiac arrest, but a spokesperson for the Los Angeles County Coroner's Office reveals a cause of death is still unknown after an autopsy was completed on Saturday (17Aug13).
The coroner is now awaiting toxicology results, which could take several weeks.
