Every day since her daughter went missing on Aug. 14, 1981, Jean McCorkle has wondered what became of her daughter Regina. Regina, the mother of an 18-month-old son, was a college student. Divorced, she worked for a janitorial service at Rock Island Arsenal. The case remains a mystery 40 years after Regina McCorkle went missing from their East Moline home. If you can help this family - even with the smallest bit of information - please call the East Moline Police at 309-752-1555.
