The incident involved a shooting in August of 2010 at L & S Auto on Highway 69 North.
Williams shot the business owner, James Sherer, and another man, Tommy Ferguson. Walker County District Attorney Bill Adair said that the victims were 70 and 74 years old, respectively, at the time of the shooting.
Witnesses said that Williams entered the dealership to inquire about a test drive, then pulled a weapon and shot the two men.
Williams, who was 30 years old at the time, fled the scene of the shooting and stole a pickup truck.
This touched off a day-long manhunt before he was arrested in Birmingham and returned to Walker County to stand trial.
A jury convicted Williams on one count of first-degree assault and one count of second-degree assault in April. Selman sentenced him to the maximum sentence for each count — 20 years for the first-degree charge and 10 years for the second-degree charge.
The sentences will run consecutively and will also run consecutive to an existing 50-year sentence on a conviction for trafficking a controlled substance.
“I agree completely with what Judge Selman said,” Adair said. “This is nothing the prosecutors or judge did to him; it’s what he did to himself. His actions are what caused this sentence.”
Sherer has passed away since the shooting, but Adair said his family was in court for the sentencing and were pleased with the result.
Adair said Williams had been serving time for that conviction at the Bibb Correctional Facility and would likely return there to finish his sentences.
