Anna Carroll, 68, was found stabbed to death and sexually assaulted in her home on the 1400 block of Ritner Street in Philadelphia on January 3, 1986. A kitchen knife was left embedded in her body. Her killing was later linked to a series of similar murders in the Frankford area between 1985 and 1990 that authorities and media associated with a possible serial offender dubbed the Frankford Slasher.

Investigators noted a pattern: several victims had been sexually assaulted and stabbed, and some were known to frequent the same local bars, suggesting a predator targeting vulnerable women. No arrest has been made in Carroll’s murder, and it remains officially unsolved. One conviction in the linked cases occurred when Leonard Christopher was arrested and convicted for the 1990 murder of Carol Dowd, but questions have been raised about whether he was the offender responsible for the Frankford-area killings.

If anyone knew Anna, frequented those bars in the mid-1980s, or has information that could help, please share what is known.
