Coweta County coroner Richard Hawk, who told The Associated Press that an autopsy began Tuesday, said Hanson, 29, was found by sheriffs Sunday "unconscious and unresponsive."
The Georgia Bureau of Investigation was conducting the autopsy Tuesday, according to the Journal-Constitution, but toxicology results could take several weeks. Hawk told The AP on Tuesday night that "the cause and manner of death are still under investigation."
Hanson died late Monday after suffering catastrophic organ failure at Atlanta's Piedmont Hospital, triggering an outpouring of emotion from the baseball community, especially former teammates on the Braves.
Hanson, 29, was at one time one of MLB's most promising young talents. He was 49-35 with a 3.80 ERA in five major-league seasons, including an 11-4 mark with the Braves in his breakout rookie season in 2009.
He was the MVP of the 2008 Arizona Fall League, which held a moment of silence for him at Tuesday's games
