It's no surprise, but the L.A. County Coroner has just made it official ... Russell Armstrong's cause of death was suicide by hanging.
We're told toxicology results are pending, but as we first reported -- no drugs or alcohol were found in the bedroom where Armstrong died Monday night.
It will take 6 to 8 weeks to complete the toxicology results.
