That '70s Show star Lisa Robin Kelly's death 'suspicious'

POLICE are investigating the death of That '70s Show star Lisa Robin Kelly after deeming her death suspicious.

Apparently, details of the troubled TV star’s death are a little murky, given a doctor at the rehab centre where Kelly was being treated pronounced her dead at 8.07am, but the Los Angeles County Coroner was not informed until midday.

Authorities became more suspicious after the rehab doctor declared Kelly had died of an embolism, but a source at the Coroner’s office has said there's no way to know if someone died of an embolism without performing an autopsy.

Though the rehab doctor has said that Kelly was taking detox drugs at the time of her death, it’s unclear if drugs played a part.

The Coroner has yet to determine what the star died of, but authorities have put a security hold on the case, meaning no information can be released while the case is being investigated.
