As noted yesterday, former WWE wrestler Andrew "Test" Martin died after overdosing on the painkiller known as "Hillbilly heroin."

The Hillsborough County Medical Examiner out of Tampa announced his cause of death as Oxycodone intoxication as a result of an accidental overdose.

Oxycodone is an addictive ingredient found in the painkillers OxyContin, Percoset and Percoden.

Martin was found dead in his Tampa apartment just four days shy of his 34th birthday on March 14, 2009 after a neighbor reported that he had appeared motionless for several hours.

The pill, dubbed "Hillbilly heroin," was also linked to the death of fellow wrestler "Sensational" Sherri Martel, not to mention Oscar-winning actor Heath Ledger.
