A former janitor at the A & P in Bowling Green, Kentucky, Avery Markham's first real job was killing his boss for $500 back in 1966. He served six years at Trambul state pen and was the cellmate of a man named Bo Crowder. Markham's life of crime was in full swing by the time Crowder was released three years later, and there was a place on his crew for his old friend.Over the next four decades they sold drugs by the truckload and killed anybody who got in their way. They became more feared with age and their legacy was cemented by those who did their dirty work.If the name Avery Markham comes up in the conversation, you best be the one doin the listenin and not the talkin.
