Authorities say a school employee in Montgomery County is facing new criminal charges after investigators allege he secretly recorded students in a changing room. Police contend the accused adult male placed a camera inside the room and left, according to reporting tied to evidence authorities reviewed. The case centers on allegations involving multiple girls at Walter Johnson High School. One report states that recovered footage dating back to 2015 prompted investigators to identify additional alleged victims, increasing the total number of girls named in the investigation. Another report describes police statements that footage shows the camera being positioned inside the changing room before the accused person exits. The outlets also describe the matter as a continuing case in which newly recovered or reviewed video leads to additional charges. The reporting describes the alleged conduct and investigative steps but does not indicate the outcome of the criminal case.
