A Cedar Rapids man faces up to two years in prison after being found guilty in Tama County on charges stemming from the traffic death of a Marshalltown man. Robert Shattuck was killed in February after being struck by a car while walking on Route 30 between Marshalltown and the Meskwaki Casino. The investigation led police to William Richard Sanders the third, in Cedar Rapids. During the trial, Sanders testified that he had hit an object while driving, but did not realize what he had hit. Several witnesses testified that they had passed Shattuck on Route 30 and knew it was a man. This led the judge to believe Sanders knew it was a person but he became scared and just kept driving. Sanders was found guilty of leaving the scene of an accident resulting in injury or death. Sentencing is scheduled for November second.
