Frank William Dale Landingin, a 19-year-old from Chicago, was last seen missing November 4, 1978 and was found dead November 12, 1978 in the Des Plaines River at Channahon in Will County. The cause of death was asphyxia; a pair of bikini briefs had been forcibly stuffed into his throat. Investigators linked his death to John Wayne Gacy on December 26, 1978 after some of Landingin’s personal belongings were found inside Gacy’s residence. Landingin was identified as Body 32 by fingerprints, dental records, and his father’s recognition.

Landingin’s death became part of the larger investigation that uncovered multiple victims at Gacy’s home. What information do readers have about Landingin’s life in Chicago or his movements in early November 1978 that could help fill gaps in the timeline?
