Katherine Anderson, 24, was last seen leaving her home in the small Chester community on Kent Island on April 20, 1979. She was expected to return that day but did not, and her family reported her missing when she failed to come back. At the time she was described as responsible with no history of voluntarily disappearing, which led investigators to consider the possibility of foul play.

Searches were conducted on land and in the water around Kent Island, and investigators followed several leads over the years, but no trace of Katherine was found and no major breakthrough was reported. The case remains an open missing person investigation and her family continues to hope for answers.

Anyone who knew Katherine, saw her on or after April 20, 1979, or has information about her disappearance is asked to come forward.
