LOS ANGELES, Aug. 19 (UPI) --
The cause of actress Lisa Robin Kelly's death won't be determined until toxicology tests are completed, officials in California said.
The process could take eight to 10 weeks, TVGuide.com reported.
Kelly, a former cast member of TV's "That '70s Show," died at a rehab facility last Wednesday after years of battling addictions to drugs and alcohol. She was 43.
