(3) people including a teen girl told law enforcement that a 42 year old Chippewa Township man who they are feuding with threw a rock at their windshield and shattered it, as they drove past.  Deputies were called to the scene on Saturday morning. The feud began after they found out the 42 year old was dating a 17 year old girl.  A report about the incident was forwarded to the prosecutors office for review.
