A Columbus man will be sentenced next month for causing a hit-and-run crash that killed a bicyclist in 2012. Matthew McQuirt has pleaded guilty to aggravated vehicular homicide charges in the death of Robert Grimm. Prosecutors say McQuirt was driving impaired along Obetz Reese Road when he hit Grimm, who was wearing a reflective vest. McQuirt told police he thought he hit a deer.
