A 61-year-old former St. Charles County police employee is facing criminal charges after prosecutors say she used her law enforcement credentials to peek into confidential databases more than 250 times for personal reasons, including searches tied to her own family. Melissa Renee Smith, who lives in St. Charles, Missouri, was charged with two counts of misuse of official information by a public servant.

The charges, filed by the St. Charles County prosecutor on September 10, allege that Smith obtained information that had nothing to do with her official duties or job performance, according to FOX 2. A probable-cause statement cited by the station says Smith conducted 259 inquiries for personal purposes over a three-year span, tapping into systems most people never get anywhere near.

Court documents described in the report say Smith pulled information from MULES, NCIC and other criminal-justice information-sharing systems, and that she used REJIS credentials to do it. REJIS describes itself as a provider of secure technology and data-management services for law enforcement, criminal-justice and other public-sector agencies, according to the organization's own website.

A Pattern That Allegedly Included Her Own Family

Investigators say a chunk of those searches followed a personal thread. In May, Smith allegedly ran 26 inquiries involving one individual, two former spouses, one immediate relative and two adult children, per the same report. She also allegedly conducted a Missouri Department of Revenue inquiry that same month concerning one individual, according to the probable-cause statement.

Two months later, in July, the pattern reportedly continued: investigators attributed 44 inquiries to a group involving a second individual, one former spouse and three adult children, and the probable-cause statement says Smith ran three more Department of Revenue inquiries concerning a second individual around the same time. The statement, as described in the station's reporting, says Smith grossly misused authorized access and violated the public trust associated with her position.

Fallout From an Earlier Flock Camera Audit

The database allegations surface months after the St. Charles County Police Department audited employee use of its Flock camera systems in August, an audit that the department's earlier reporting says revealed an employee had abused those cameras for personal reasons. That employee resigned following the audit, and the department discontinued its use of Flock cameras altogether that same month, the outlet's prior coverage notes.

Smith's initial court appearance is scheduled for October 29, according to Missouri court records referenced in the report. It remains unclear from the available record whether the Flock camera audit and the database allegations against Smith stem from the same investigation or involve the same conduct.

Not an Isolated Case Nationally

Cases like this aren't unique to St. Charles County. In Texas, former Lufkin officer Zach Klein faces 100 counts of misuse of official information following a Texas Rangers investigation tied to alleged misuse of Flock camera data, according to CBS19. The scale of that case dwarfs the two counts Smith faces, but both point to growing scrutiny of how officers and civilian staff use surveillance and database tools meant for official police work.
