The Frankford Slasher is the name given by the media to a possible serial killer who operated in and around the neighborhood of Frankford in Philadelphia, Pennsylvania from 1985 to 1990. Leonard Christopher was convicted in the murder of one of the nine supposedly linked victims, but the others remain unsolved. All the victims were sexually assaulted and stabbed to death. Several of the victims were seen with a middle-aged white man shortly before their deaths. Possible victims Helen Patent, 52, killed August 19, 1985 Anna Carroll, 68, killed January 3, 1986 Suzanna Olszef, 64, killed December 25, 1986 Jeanne Durkin, 28, killed January 8, 1987 Catherine M.

Despite the fact that he did not match the witness's description, and that there was no evidence to link him to any of the other eight murders, and only circumstantial evidence linking him to Dowd's murder, he was tried and convicted of one count of first degree murder on December 12, 1990, and sentenced to life in prison. He has since died of cancer, maintaining his innocence since the beginning.
