On June, 13, 1965, 2-year-old Elizabeth Ann Gill, known as “Beth,” vanished while playing in her yard in Cape Girardeau, Missouri – just a few blocks from the Mississippi River. Dateline’s Josh Mankiewicz speaks with two of her nine siblings, Martha Gill Hamilton and Jeannie Gill Hinck, and Bobby Newton of the Cape Girardeau Police Department. Both police and the family believe Beth may have been abducted and raised by another family, and could still be alive. They are hopeful DNA and ancestry websites will lead them to Beth, who likely would not remember being abducted. Beth would be 60 years old today. If you have any information about her case, or you believe you might be Beth, call the National Center for Missing and Exploited Children at 1-800-THE-LOST.
