April Irene Vlk, 37, was last seen on Hilton Head Island, South Carolina, on September 17, 1991, after a disagreement with her boyfriend at their Sea Side Villas apartment. She was reported missing by her father on October 23, 1991, after he could not reach her.

Witnesses at a local church said a woman matching April’s description came in barefoot with bleeding feet, appeared terrified and cried, and wrote Washington, D.C. on a piece of cardboard, saying she planned to hitchhike off the island. Church members gave her twenty dollars to buy shoes; she left and was never seen again. April was described as white, dark blonde hair, green eyes, pierced ears, and had back problems requiring medication. She worked in printing and medicine and enjoyed boating.

It is unknown whether she left the island or suffered foul play. Anyone who knew April, saw her that week, or has information about her movements after September 17, 1991, is asked to come forward.
