(CNN) - Trayvon Martin had drugs in his system when he was fatally shot earlier this year by George Zimmerman in Sanford, Florida, according to autopsy results released Thursday.
Martin's blood contained THC, which is the psychoactive ingredient in marijuana, according to an autopsy conducted February 27 - the day after the teenager was shot dead.
Toxicology tests found elements of the drug in the teenager's chest blood - 1.5 nanograms per milliliter of one type (THC), as well as 7.3 nanograms of another type (THC-COOH) - according to the medical examiner's report. There was also a presumed positive test of cannabinoids in Martin's urine. It was not immediately clear how significant these amounts were.
He died from a gunshot wounded to chest fired from "intermediate range," according to the medical examiner's report, which was one of several documents on the case released Thursday by the office of special prosecutor Angela Corey.
