b. Rules for closed investigations.

Once an investigation is closed, investigatory files are subject to disclosure, based upon an amendment to the comparable FOIA exemption. See Fioretti v. Maryland State Board of Dental Examiners, 351 Md. 66, 716 A.2d 258 (1998); Bowen v. Davison, 135 Md. App 152, 761 A.2d 1013 (2000).  Once an investigation has been closed, disclosure is considered less likely to be "contrary to the public interest." City of Frederick v. Randall Family, LLC, 154 Md. App. 543, 562-567, 841 A.2d 10 (2004), Prince George's County v. Washington Post Co., 149 Md. App. 289, 33, 815 A.2d 859 (2003).  Where the internal police investigation concludes with a determination that the allegations are not sustained, fairness to the investigated officers and the avoidance of needless publicity to the cooperating witnesses, with possible inhibiting effects on future investigations, justify on public interest grounds, the custodian's denial of inspection to one other than a person in interest. Mayor and City Council of Baltimore, v. Maryland Comm. Against the Gun Ban, 329 Md. 78, 617 A.2d 1040 (1993).
