Burnside was driving to an afternoon church event on April 7, 2013, when he lost control of his vehicle on a highway exit ramp in Sun Prairie and hit Mengelt, who was out for a Sunday training run. Prosecutors allege Burnside fled the scene in his vehicle. Police first spoke with him at a nearby gas station.
A preliminary breath test determined he had a blood alcohol level of 0.128 percent, according to the criminal complaint. The legal limit for driving in Wisconsin is 0.08 percent.
