Sarah Walker was found guilty Friday in Leon Circuit Court of DUI manslaughter stemming from a April 2014 school bus crash that killed William "Rusty" Fowler.

A sentencing date has not been determined for 28-year-old Walker, who made left a turn at Conner Boulevard and Apalachee Parkway and collided with a school bus driven by Fowler. The crashed caused the bus to strike a power pole.

The case was declared a mistrial last year when Assistant State Attorney Georgia Cappleman sought to introduce last-minute blood work on Walker's alcohol levels the night of the crash that took place in the pouring rain. Walker's attorney called for a mistrial and said he didn't have an opportunity to depose the technician who executed the new test.

On Friday, Cappleman said her office has been trying to reach a resolution since 2014, adding "it's been a long time coming."

"It's been slow justice for the family of Mr. Fowler. I'm really glad we were able to establish a guilty verdict," Cappleman said.
