“This is an active investigation and the detectives have leads,” a report states. “The police department must continually balance the need to inform the public against releasing information that could jeopardize the investigation and potential suspect identification. Future apprehension could be made more difficult and dangerous if suspects are alerted to the details of the police investigation.”
