In 1976, Duane "Dog" Chapman was convicted of first-degree murder relating to the death of Jerry Oliver in Pampa, Texas, according to The Guardian. Oliver, an alleged drug dealer, was 69 when he died.
At the time of his arrest, Dog (pictured above) was married to La Fonda Sue Honeycutt, the mother of his eldest sons, Leland and Duane Lee. "Even though I was married, I was still enjoying the biker life, whoring around, smoking pot, and drinking whiskey until I was completely out of control," he said about his mindset before the crime. And on the night in the question, Dog decided to go out with his pals despite a warning from Honeycutt. "La Fonda warned me not to go out with the boys that night," he wrote in his 2007 memoir, You Can Run But You Can't Hide. "She had a great ability to foresee things. I wish I had listened to her."
As for the murder, it occurred when Dog and his pals arrived at Oliver's house to buy marijuana. While Dog was outside waiting in the vehicle, one of his buddies got into an argument with Oliver and fatally shot him, as he recalled to the Toronto Star. The dad was sentenced to five years in prison but was paroled after 18 months. "In Texas in the '70s, if you were present, you were just as guilty," he explained to the outlet.
