Lisa Robin Kelly's Cause of Death Determination Awaits Toxicology Results
She passed away earlier this week and an autopsy was performed on Saturday, but Lisa Robin Kelly's cause of death is still unknown.
According to a coroner's office spokeswoman, it will take two months for toxicology results to come back from the lab.
On Wednesday, the "That '70s Show" star died in her sleep at a treatment facility to help treat her various addictions.
Though she's battled the demons for years, her death was a shock, as her agent Craig Wyckoff told PEOPLE, "I spoke to her on Monday, and she was hopeful and confident, looking forward to putting this part of her life behind her."
