Priscilla was born as Priscilla Wilborn. She was in a poor family, but she was so beautiful that she attracted some of the richest men in Texas. She was a flamboyant woman whom openly flaunted her wealth. She was married to one of the richest men in Texas, T. Cullen Davis. She filed for divorce in 1974 and claimed Cullen was abusive. Cullen was as reserved as Priscilla was flamboyant. They couldn't stand each other. The divorce was messy, and Cullen was forced to pay Priscilla 5,000 dollars per month for separate maintenance, and another 52,000 dollars in legal fees.
A killer entered the Mockingbird Mansion and found Andrea Wilborn. He took her to the basement, and had her kneel down. He then shot her in the chest.
Then, Priscilla and Stan came in. The killer shot Priscilla Davis in the chest, but she survived. Priscilla helplessly saw the killer shoot Stan Farr in the neck. Stan was athletic, however, and struggled with the killer. The killer shot Stan dead with four more shots. Priscilla ran off away from the mansion, but collapsed. The killer than started to drag her into the mansion. Priscilla was calling the killer "Cullen", because he was likely her husband.
Beverly Bass, a friend of Priscilla's older daughter Dee, was accompanied by 22-year old Gus "Bubba" Gavrel, when she and Bubba found Priscilla being dragged aside. The killer injured Gus with a shot from his gun. Gus helplessly watched the killer go after Beverley. Priscilla was able to put enough distance between the killer and Bass, so Bass was able to get the attention of a passing car and escape the killer with Priscilla.
Police found 30-year old Stan Farr in a pool of blood at the mansion, and they also found Andrea Wilborn dead.
T. Cullen Davis was tried and found innocent for the murder of Andrea Wilborn. He allegedly had a plot to kill Judge Joe Edison, Beverly Bass, and Priscilla. Davis was arrested for this but was acquitted of this and a civil suit.
Priscilla died from breast cancer. She had never remarried, and her self worth had plummeted. The rest of her life was quiet.
