We're told the Coroner has a number of questions about things she knows about Russell, including:
-- Russell's medical history -- Medication history -- References he may have made about suicide -- State of mind in the weeks preceding his death
As TMZ first reported, Taylor was on the property where Russell committed suicide when his body was discovered, however she left before the Coroner arrived. The Coroner's office has contacted Taylor about an interview, but they have not heard back from her.
The Coroner has already determined ... the cause of Russell's death was suicide by hanging, but the toxicology report is still pending.
