Attorney Guy Womack said Friday that Cpl. Robert Richards died Wednesday at his home in Jacksonville. Womack says he suspects a change in medicine caused the death. Richards was taking medicine for numerous injuries. He was 28.
Womack says neither foul play nor suicide is suspected.
Richards was a sergeant who was demoted to corporal in August 2013 after a video was shared on YouTube, showing him and three other Camp Lejeune Marines urinating on the bodies of three Afghans in July 2011.
Womack called him a hero and says Richards made a mistake during his third tour in Afghanistan.
