It might be that the actual cause of death is finally determined.
Ironically a person I knew from high school died the same way last October. It seems alcohol and exhaustion coupled with hot bath water are a pretty lethal combination. For my deceased friend, it was months before the coroner determined the death was accidental, a combination of alcohol, hot water and exhaustion.Given her husband awoke to find her drowned in the bathtub, I guess officials wanted to be sure that was all it was.
