A statement issued from his wife.
"Robin's sobriety was intact and he was brave as he struggled with his own battles of depression, anxiety,as well as early stages of Parkinson's Disease, which he was not ready to share publicly.
It is our hope in the wake of Robin's tragic passing, that other's will find the strength to seek the care and support they need to treat whatever battles they are facing so that they may feel less afraid."
