An autopsy report is revealing more details about the cause of Roy Halladay's death.
Roy Halladay, who spent 12 seasons with the Jays, was flying in his two-seater plane over the Gulf of Mexico when it crashed on Tuesday.
TMZ reported the sleep aid was a generic form of Ambien.
However, the Tampa Times also reports the autopsy showed signs of some powerful medications in Halladay's system at the time of his death.
Halladay's ICON 15 aircraft flew very close to homes and near the water before crashing on November 8, the National Transportation Safety Board said. According to Spectrum Bay News 9, his blood-alcohol content was 0.01 percent.

The report also reveals that Halladay suffered a subdural hemorrhage, multiple rib fractures, a leg fracture and injuries to his lungs, liver and spleen.
