Christine Marie Sexton, 36, of Turlock, California, vanished after leaving the Office Cocktail Lounge in the early hours of April 17, 1989. She was seen after 2:00 a.m., talking with a man in the parking lot before getting into her 1984 Oldsmobile Cutlass Supreme and driving off. Friends had been with her earlier that night.

Ten days later the car was recovered submerged in an irrigation canal near Turlock Lake. The windows were rolled up, the keys were in the ignition, and clothing and groceries were found inside, but Sexton’s purse was missing and there was no sign of her. Investigators have suspected foul play and noted possible ties to drug traffickers; they say they have persons of interest but no one has been charged.

What information do readers have about Christine’s last night or the man seen with her in the parking lot?
