Patricia Palmer was 19 in 1981, a newlywed hoping to earn enough money from the sale of her wedding dress to help with a down payment for a house. On Nov. 15, 1981, she placed an ad in the Tulsa World. Two days later, a man called the number listed, her motherís number, to answer that ad. The prospective buyer arranged to meet Palmer at her motherís home at 4127 S. Sandusky Ave. on Nov. 17, 1981, to view the dress. Later that afternoon, when Palmerís mother called and her daughter did not answer the phone, a neighbor was contacted and found the new bride dead. She had been sexually assaulted, strangled and drowned in the bathtub. DNA had been collected in the case, according to news reports.

Subject's vehicle parked in the driveway was a black over dark blue 1972-74 Chevrolet Impala. The vehicle had an Oklahoma license plate. The vehicle was very clean, possible recently repainted. Chrome dealer decal on left side of the bottom of the trunk lid. The vehicle may have had a black CB antenna mounted in the center of the trunk lid, or a fully extended radio antenna that was bent back over the top of the vehicle.

Tulsa's cold case homicide squad is asking for help in a 1981 murder that still haunts them to this day. Patricia Palmer was the victim, a newlywed who put an ad in the paper to sell her wedding dress. Police say the man who showed up to look at it strangled her to death...

The semen from the scene was destroyed because at that time, samples were kept in test tubes. However, police do have DNA from gum found in the bathtub that could still help solve this case.
