George Trepal: Murder by Means of a Rare Poison

Last week’s blog underscored the old saw about there being no honor among thieves. This week, our topic is George Trepal, a murderer with a genius IQ.

Problems with the Neighbors

Two families lived next to each other amid the orange groves of the tiny town of Alturas, Florida. In one house, mine worker Parearlyn “Pye” Carr lived with his wife Peggy and their children from previous marriages. Even though they had only been married for a few months, Peggy suspected her husband of having an affair. There was also frequent strife among the children, who were in their teens and early twenties.

The other family was George Trepal and his wife, Dr. Diana Carr (no relation to Pye). George was a chemist and Diana an orthopedic surgeon who people said dominated George. Both belonged to Mensa, a society for people with high IQ.

You’d think two families living close together with no other neighbors nearby would form a bond but not in this case. The two families argued frequently over things like firecrackers and loud music. It seemed that Diana and Peggy’s stepson, Duane, were frequently at odds. And on one occasion, Peggy and Diana had a ferocious altercation over Duane’s alleged bad behavior.

A Strange Illness — And Death

Peggy Carr worked in a local restaurant. One day her daughter, Sissy, visited her at work. Peggy complained she didn’t feel well, and Sissy urged her to go home. Her youngest son found her lying on a sofa, unable to speak. Her family rushed her to a hospital.

At the hospital, doctors spent three days running tests but couldn’t find anything wrong. They suggested that perhaps Peggy’s symptoms were psychosomatic—all in her head. But her symptoms slowly disappeared in the hospital, so the doctors sent her home. The symptoms returned almost immediately.

Again, Peggy couldn’t speak. She was able to write a note saying, “My feet are killing me.” As they drove Peggy back to the hospital, her son Travis and stepson Duane both started feeling a burning sensation in their own feet. Now doctors suspected poisoning. They thought it might be a metallic substance like arsenic. But when Peggy began to lose her hair, they suspected the poison was thallium.

Peggy slipped into a coma, while doctors put Travis on a respirator. Peggy died in March 1988 after Pye allowed the hospital to take her off life support.

Detectives Find Thallium and Finger George Trepal

Detectives tested the Carr’s well water and dozens, if not hundreds, of items around the house. They found no thallium until they noticed an eight-pack of Coca Cola under the kitchen counter. Four of the bottles were empty and all four contained traces of thallium.

Product tampering is a federal crime, so the FBI was now involved. They found that someone had deliberately opened the bottles in the eight-pack. Since one else in the area developed symptoms of thallium poisoning, investigators concluded that someone had targeted the Carr family.

Naturally, Pye was the initial suspect. But authorities doubted he would poison his own son. Besides, tests showed that Pye himself had consumed thallium. Investigators widened their circle and began to consider the oddball neighbor, George Trepal.

George Trepal was an intelligent but passive man. Even the Carr family thought he was harmless. But George Trepal wasn’t harmless. A self-taught chemist, he had a 1975 conviction for manufacturing methamphetamine for sale. When questioned about the Carrs, he was nervous and complained at length about things that seemed trivial to detectives. Detective Susan Goreck befriended him and got to know him well. He told her he hated people less intelligent than himself and people he couldn’t control. Both traits applied to the Carrs.

George Trepal Arrested and Convicted

Eventually the FBI found traces of thallium in a small bottle in Trepal’s garage. They arrested him and charged him with murder. They also found a room in his house full of BDSM paraphernalia. The supposedly meek Trepal appeared to have a vivid fantasy life.

George Trepal refused a plea deal that would have sent him to prison for life. Instead, he went to trial. A jury found him guilty and, on March 16, 1991, the judge sentenced him to death.

Epilogue

Dr. Diana Carr died at age 69 in 2018 from complications following a stroke. George Trepal still sits on Florida’s death row. He maintains his Mensa membership and continues to file appeals, all of which have failed.

Detective Susan Goreck and Jeffrey Good wrote a book about the case, Poison Mind.
