Florence Janette Filatreau, a 51-year-old white female and mother of three sons, was a resident of Old Louisville, a historic neighborhood in Louisville, Kentucky, known for its Victorian architecture. Her life was tragically cut short in a deliberately set fire that would haunt the city and her family for years.
In the pre-dawn hours of Thursday, July 2, 2015, a fire broke out in the three-story apartment building at 1133 S. 2nd Street where Florence lived. The blaze, which started just before 8 a.m., moved with terrifying speed, engulfing the structure and trapping residents inside. First responders arrived to a scene of chaos and desperation, with people screaming for help from their windows. The fire was so intense that two residents were forced to jump from third-story windows to escape, sustaining serious injuries. A firefighter also became trapped when a stairwell collapsed and was injured during the response.
Firefighters found Florence Filatreau and another resident, 51-year-old Theresa Shultz, deceased inside their second-floor apartments. The coroner later determined that both women had died from smoke inhalation. A third resident, John Bullock, who had only moved into the building four days earlier, was critically injured with third-degree burns and smoke inhalation. He succumbed to his injuries a week later, on July 9, becoming the fire's third victim.
Investigators from the Louisville Fire Department's Arson Bureau and the federal Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) quickly determined the fire was no accident. They found that it had been intentionally set on a staircase, and the case was officially classified as a triple homicide investigation. In the immediate aftermath, police sought tips from the public and released surveillance video of a person of interest seen leaving the building shortly before the fire was reported, but the individual remained unidentified for years. The case grew cold, leaving the families of Florence, Theresa, and John with unanswered questions and a profound sense of loss.
For years, investigators diligently pursued the case, facing challenges that included deceased witnesses and limited evidence. The breakthrough finally came in October 2022, more than seven years after the fire, when a witness came forward with a crucial tip that identified a suspect. After further investigation to corroborate the new information, Louisville Fire officials publicly identified the arsonist on September 4, 2025. The suspect was named as Michael Robertson.
Tragically, there would be no trial or conviction. Investigators revealed that Robertson had died in 2023, two years before he was publicly named. Had he lived, authorities stated he would have faced charges of arson and murder for the three lives he took. While the suspect's death meant he would never be held accountable by the justice system, the resolution brought a measure of closure to the victims' families.
In September 2025, Louisville's mayor and fire chief honored the four lead investigators from the Louisville Arson Bureau and the ATF for their decade of persistent work. During the ceremony, the fire chief shared an emotional voicemail from one of the victim's brothers. "I heard that you found the guy," the man said, choking up. "I personally want to tell you thank you, thank you, thank you for everything y'all do. It means so much to me… I cannot believe this is happening, but I knew it would 'cause y'all never give up." The case is now considered closed.
