Karen Faye Heim, 42, of Sand Springs, Oklahoma, went missing around Christmas 2005 after leaving her parents’ home in Tulsa about 8:30 PM on December 25, 2005. Her family said she had been in good spirits despite a history of depression. Witnesses later reported seeing her on December 26 in both Tulsa and Sand Springs, creating uncertainty about her final movements.

On December 27, 2005, Karen’s 1988 tan Buick Electra was found abandoned on a farm road near Clarksville in Red River County, Texas, not far from the Oklahoma border. The car’s doors were open and the interior had been wiped clean of fingerprints, yet personal items including her purse, keys, driver’s license, Social Security card, and money remained inside, suggesting theft was not the motive. Her family said she had no known connections in that area.

Foul play is suspected. Investigators have noted that Karen had recently served as a witness in a drug case involving her ex-husband, though no definitive link to her disappearance has been established. Karen is described as 5 feet 4 inches, 130–140 pounds, with long brown hair, blue eyes, and a cross tattoo on her ankle. Does anyone who knew Karen or who was in the Tulsa–Sand Springs area on December 25–27, 2005 have information that could help?
