Chester Bennington autopsy reveals use of alcohol

Chester Bennington's autopsy showed he had a trace amount of alcohol in his system when he hanged himself, TMZ has learned.

According to the autopsy and toxicology results, obtained by TMZ, the Linkin Park singer's blood also tested "presumptive positive" for MDMA (ecstasy) based on one test. Two subsequent tests did not detect the drug, and the ultimate conclusion was Chester was not under the influence of drugs when he died. 

Authorities found a prescription bottle of Zolpidem - generic Ambien - on his dresser. There was also a pint glass of Corona, which was less than half full - and an empty bottle of Stella Artois.
