(Richmond, IN)--A teenager has undergone an overnight surgery at Miami Valley Hospital after being shot in Richmond Sunday.  It happened late Sunday afternoon at a bridge over the East Fork of the Whitewater River at the north end of North 17^th.  Richmond police investigators say the boy was found in or near the river and that life-saving efforts were immediately rendered.  The boy was carried across the river to a waiting ambulance, taken to Reid Health, and then flown out to Miami Valley.  Police then interviewed a second juvenile and transferred that teen to a juvenile detention center.  RPD’s release made no mention of the relationship between the two or what led to the shooting, but friends and family members have indicated that they knew each other and got into an argument while fishing.
