Michelle Dehner, a 30-year-old White woman, was stabbed to death in her Philadelphia apartment on September 6, 1990. She was found inside an Arrott Street residence near Frankford Avenue with multiple stab wounds — published accounts report about 23, concentrated in the chest and abdomen. Her killing drew immediate attention because it resembled a string of brutal attacks linked to the so-called Frankford Slasher, a sequence of victims repeatedly stabbed or slashed and sexually assaulted beginning in 1985.

At the time Dehner was murdered, Leonard Christopher was already in custody awaiting trial for the April 1990 killing of Carol Dowd, which meant he could not have committed Dehner’s homicide while jailed. Christopher was later convicted in the Dowd case, but police noted he did not match witness descriptions associated with other suspected Slasher victims. Some reports treat Dehner as a possible final Slasher victim; others classify her death as a possible copycat. No arrest, charge, or conviction has been reliably reported for her murder.

Does anyone have memories or information about the Frankford area in 1990 that could shed light on Dehner’s case?
