Investigatory records generally are subject to the common law balancing test. Appleton Post-Crescent v. Janssen, 149 Wis. 2d 294, 441 N.W.2d 255 (Ct. App. 1989). Journal/Sentinel Inc. v. Aagerup, 145 Wis. 2d 818, 429 N.W.2d 772 (Ct. App. 1988). Investigatory records in the hands of the district attorney are absolutely immune from public inspection. State ex rel. Richard v. Foust, 165 Wis. 2d 429, 477 N.W.2d 608 (1991). Juvenile investigatory records are not open to inspection except for news gatherers who wish to obtain news without revealing the identity of the child. Wis. Stat. § 48.396(1).
