Cora Christmas McGuirk, born December 25, 1968, vanished from Seattle in the summer of 1991 at age 22. A mother of three, she had moved to Washington after high school, briefly worked at the University of Washington Medical Center gift shop and enrolled in electrical engineering before dropping classes and leaving her job. In the months before her disappearance her life was unsettled; she had periodically gone missing for a couple of days, and was dating a man involved with drugs.

Cora was gone for two days in early July 1991, returned acting strangely, and told her aunt Beulah Walker to take care of the children if anything happened to her. She left again on July 12, 1991, and was never seen or heard from afterward. Her car was later found abandoned near Aurora Avenue North, an area linked to the Green River Killer, leading investigators to consider him a possible suspect. Her body has never been found and the Seattle Police Department still lists her as missing.

If anyone knew Cora, her movements in July 1991, or has information about the location where her car was found, please share what you know.
