Mystery Cloaks That '70s Show Actress's Death

That '70s Show actress Lisa Robin Kelly was pronounced dead by a doctor at her LA rehab facility at 8:07am Thursday, but the county coroner reportedly didn't learn of the death until noon ... when someone from the office read about it on TMZ. Law enforcement sources tell TMZ no one from the rehab facility called the county coroner—and now both the coroner and the LA County Sheriff's Department are suspicious and are investigating Kelly's death. Another cause of their suspicion: The rehab doctor said an embolism caused Kelly's death, but the coroner says there's no way he could have known that without doing an autopsy.

Kelly's autopsy was completed over the weekend, but her official cause of death is not yet known. The doctor also told the coroner Kelly was on detox drugs when she died, sources say, but it won't be clear whether they played a role in her death until the toxicology report is in. Meanwhile, Kelly's estranged husband (who earlier blamed Kelly's new boyfriend for the actress' recent troubles) is blabbing away about her death in a National Enquirer article picked up by Radar. He says the 43-year-old had a congenital heart defect, and that back in 2011 she was drinking as much as a half-gallon of vodka per day. "You can't do to the human body what Lisa did, for the length of time that she did, and expect to survive," he says. Click for more. (More celebrity stories.)
