Prosecutors have dropped the felony assault case against Missouri City police officer Robin Williams, nearly three years after her arrest during her campaign for Houston mayor.

Harris County court records filed Friday, Oct. 2, show prosecutors asked a judge to dismiss the charge of continual assault of a family member. The reason: the accusations could not be proved beyond a reasonable doubt, FOX 26 Houston first reported.

Prosecutors gave no further details about the dismissal.

Williams, a Missouri City Police Department officer, was arrested in 2023 after being accused of using her department-issued baton and taser to assault her live-in boyfriend. Court documents allege she punched the man and struck him with her baton during a New Year's Eve argument.

Authorities also reviewed video evidence from a separate incident in August in which Williams allegedly used the baton to hit him multiple times, according to court documents. The boyfriend also told investigators that Williams grabbed her taser and shot him with it after another argument, court documents state.

Williams had announced her campaign for Houston mayor before the allegations surfaced. She continued her campaign but did not win.

In a January 2023 interview with FOX 26, Williams denied being violent toward her fiancé and denied striking him on New Year's Eve. "I did not strike him," she told FOX 26's Jonathan Martin at the time.

The Missouri City Police Department placed Williams on administrative leave after her 2023 arrest. Whether she remains employed with the department is unclear. No statement from the department regarding the dismissal appeared in public records as of Saturday, Oct. 3.

Williams had been free on a $15,000 bond. A jury trial had been scheduled for Jan. 20, but the case was dismissed before it went to trial.

Prosecutors could refile the charges. No timeline for that decision has been announced.
