One man’s under arrest in Lee County in the hit-and-run death of a Keokuk man whose body was found along Highway 218. Investigators say the 22-year-old man had been walking north along the road early yesterday morning when he was hit from behind. Later in the day authorities arrested 18-year-old Ian Arne at his Montrose home, and charged him with leaving the scene of a fatal accident, an aggravated misdemeanor. The Keokuk police and Lee County sheriff’s investigators had been searching for a green car with damage to the right front, and they impounded Arne’s car as part of the investigation. The dead man’s been identified as James Clemens of Keokuk.
