A preliminary review has indicated the officer who responded to the earlier reports went in error to the 1500 block of Stonewood Road instead of the 1600 block, and police are trying to determine the reason, Jablow said. But the department is also investigating whether the officer ever got out of his vehicle to look for potential victims, shell casings or other evidence of a shooting once he arrived in the area — as is required when responding to reported gunfire, Jablow said.
