A Cincinnati man has admitted in federal court that he stalked neighborhood porches with fire, torching Pride flags, a Ukrainian flag, and other decorations outside homes in Northside and Clifton during a late‑July spree that rattled residents and LGBTQ advocates alike. Thomas Brian Niehaus, 52, pleaded guilty this week in federal court to malicious use of fire after investigators say he set a string of small porch fires while shouting homophobic slurs and threats. The federal plea lands as Niehaus also faces state arson indictments in Hamilton County, and the case has revived a heated local debate over protections for LGBTQ residents and the limits of Ohio’s hate‑crime statutes.
According to a press release from the Hamilton County Prosecutor's Office, the incidents happened on July 30, 2025, and involved seven Pride flags, one Pride decoration, and a yard sign featuring a Ukrainian flag, nine flags or buntings in all, most of them attached to homes in the Northside and Clifton neighborhoods. The prosecutor's office announced an indictment charging Niehaus with seven counts of aggravated arson and three counts of arson tied to those burnings and described the conduct as "targeted, hateful attempts to intimidate and silence members of our community."
Surveillance video and court documents reviewed by local outlets show a person stepping onto porches, using a tiki‑style torch to ignite flags, then pedaling away on a bicycle while yelling slurs and threats. In one clip, the person can be heard saying, "I hope it burns your f—ing house down," and other footage captured additional violent taunts, according to reporting by Law & Crime. Fire investigators cautioned that because the flags hung so close to the houses, the relatively small porch fires could easily have grown into major blazes.
Investigators say they zeroed in on a suspect after gathering home surveillance video and data from the Red Bike rental system, then took Niehaus into custody, officials told FOX19. The Cincinnati Fire Department’s Fire Investigative Unit credited neighborhood tips and shared video for speeding up the case, and authorities reported that no one was physically hurt in the series of burnings.
Niehaus pleaded guilty in federal court to one count of malicious use of fire, according to the Cincinnati Enquirer. During his plea hearing, he told the judge he had previously performed as a violinist, saying he played with a New York City quartet and with the Boston Pops Orchestra, and that he graduated from Cincinnati’s School for Creative and Performing Arts, the Enquirer reports.
Legal consequences and next steps
Federal prosecutors say the malicious‑use‑of‑fire conviction carries a mandatory minimum sentence of five years, and court records show Niehaus faces a potential federal sentence ranging from roughly five to twenty years. U.S. District Judge Michael Barrett told those in court that any state sentence would run at the same time as the federal term, according to the Cincinnati Enquirer. Separate aggravated arson and arson charges are still pending in Hamilton County and can proceed independently of the federal case.
Community response
Hamilton County Prosecutor Connie Pillich labeled the burnings "targeted, hateful attempts to intimidate and silence members of our community," and Cincinnati Pride stated that hatred and violence have no place in the city, according to the prosecutor’s release. Neighbors told local reporters the fires left them shaken; some residents said they intend to put up even more Pride flags in defiance, while others are pressing for stronger legal tools to deal with bias‑motivated property crimes.
Prosecutors and defense counsel are expected to return to federal court for sentencing, and any remaining hearings, and state proceedings will continue in Hamilton County. Officials are asking anyone with additional footage or information to contact investigators as local leaders and residents watch to see how the case, and the broader legal questions surrounding it, unfold.
