The Tampa Bay Times reports that an autopsy released Friday shows the former Blue Jays and Phillies All-Star died from blunt force trauma with drowning as a contributing factor when he crashed his personal plane into the Gulf of Mexico near New Port Richey on November 7.
The toxicology results show Halladay had zolpidem (the generic name for Ambien), as well as morphine in his system at the time of the crash. "His body also had evidence of amphetamine, morphine, and a drug typically used to treat insomnia", according to the Tampa Bay Times.
The report noted that the morphine found in his system could have been caused by using heroin, but TMZ claims to have sources that say Halladay was never known for using the addictive drug.More news: Manchester United set to reveal Mourinho Contact extension

However, a source familiar with the autopsy told the website that the pitcher's results were consistent of someone using perscription medication.
Nicotine and alcohol were also discovered in Halladay's blood, the autopsy found. The plane's chief test pilot died in a crash involving the same model last May, according to CNN.
Several nearby boaters confirmed TMZ's report that the pitcher's plane was "dramatically increasing and decreasing in elevation". During his time in Major League Baseball, he won the Cy Young Award twice and pitched a no-hitter in the 2010 playoffs. Among his achievements the year were a flawless game against the Florida Marlins on May 29, and a no-hitter against the Cincinnati Reds on October 6 in Game 1 of the National League Division Series.
