On Tuesday, September 8, 1987, 27-year-old Debra Jean McClendon finished work at a chiropractor’s office in Ardmore, Oklahoma, and went to the Mountain View Mall. Friends saw her shopping that evening. When she didn’t return home her husband, Dennis McClendon, and her father began looking for her; her father found her body inside her red and silver pickup truck in the mall parking lot.

Investigators concluded Debra had been shot at close range in the back of the head with what was believed to be a large-caliber handgun. Robbery was ruled out: her wallet and jewelry were left undisturbed in the truck. No witnesses to the shooting were identified, and no arrests have ever been made; the homicide remains unsolved.

Family members reportedly suspected her husband or people he associated with. At the time the couple had recently bought a new home, and rumors about owed drug money and a life insurance payout have been mentioned. The husband has declined interview requests, and a brother-in-law later cited the unsolved murder as a reason for becoming a police officer.

Did anyone see Debra at the Mountain View Mall that evening or have information about her movements before the shooting?
