After Dan and his brother were charged for the murders of their sister-in-law, Brenda, and her infant daughter, Erica, Dan claimed he was responsible for both homicides.
As as result, the brothers stood separate trials, and according to The Cinemaholic, the jury found Dan guilty of two counts of first-degree murder after he chose to “represent himself with access to a standby counsel.” Ron, on the other hand, was found guilty of capital murder in 1985 and was sentenced to death.
