It was back in August when we got word that former Warrant lead singer Jani Lane had been found dead in his hotel room in California.  The coroner's office has finished conducting it's investigation and have determined an official cause of death.

The investigation by the LA County Coroner's office on Jani Lane has been completed and they now know his cause of death.  TMZ reports that the official cause was alcohol poisoning.  According to the coroner's report, he died from "acute ethanol poisoning".

Jani was found dead in his hotel room on August 11, 2011 and had suffered from substance abuse problems in the past.  He was 47 years old.  Hopefully this is now closure for his friends and family who were left wondering.
