Crystal Gayle Hall, 24, disappeared from Pikeville, Kentucky in early March 2009 after visiting her sister’s apartment on Kentucky Avenue. Known to family as Red for her hair, she was last heard on a phone call with a friend during which she reportedly said someone was coming in the back door before the call abruptly ended. Friends checked the apartment the next day and found Crystal gone; her purse, coat and other personal items remained inside and she did not own a vehicle.

A mother of three who had struggled with drug addiction and spent a year in jail on drug charges, Crystal’s grandmother had custody of two of the children and says Crystal called them every day until she vanished. Her ex-husband was incarcerated at the time and is not considered a suspect. Investigators found no records of bus or plane tickets, and several reported sightings were never confirmed.

The last phone call is a focal point but its meaning is disputed by family who say the phrase someone was at the door was sometimes used casually to end conversations. Does anyone living in Pikeville in March 2009 remember unusual activity near Kentucky Avenue or have information about Crystal’s last known movements?
