Lillian Halpin was a 59-year-old widow who managed the apartment complex where she lived on the 9400 block of N. St. Louis Avenue in Portland, Oregon. Friends and relatives grew concerned after several days without contact; she was last heard from the evening of September 8, 1982, and on the afternoon of September 12, 1982 they found her apartment and learned she had been strangled to death.

Investigators found little to suggest why Halpin would be targeted. She had no criminal history, no reported involvement with drugs, and no known boyfriend at the time of her death. No arrests have been made and no specific suspects have been publicly identified; the case remains an open, unsolved homicide and is now a cold case.

If anyone knew Lillian, lived in that neighborhood in 1982, or has information about people who might have been in or around the building in early September 1982, please come forward with what you know.
