Kristine Pierson was 24 and working as a model when her body was found burned in an alley in Louisville’s Portland neighborhood on the morning of January 17, 2014. Family say she had no connection to that area. The autopsy was inconclusive and an official cause of death was not determined, but investigators classified the death as a homicide because of the circumstances and the extensive burns to her remains.

Her mother, Cheryl Browning, had been preparing to file a missing person report after Kristine stopped communicating with family; the last known sighting was three days earlier, on January 14, when surveillance footage showed her getting into a vehicle downtown. That car was a rental leased by a woman who, when contacted by police, retained an attorney and declined to cooperate. The man seen driving the vehicle has not been identified. Detectives have interviewed persons of interest and collected DNA evidence, but no arrests have been announced. A surveillance camera in the alley wasn’t working the day the body was found.

If anyone knew Kristine’s movements in mid-January 2014 or saw that rental car downtown, please come forward with information.
