William Davis, a serial killer, has been condemned to death for killing at least four patients while working at a hospital in Tyler, Texas.
On Wednesday afternoon, after nearly two hours of discussion, a jury reached a verdict and sentenced Davis to death.
According to the Associated Press, Davis, who worked as a nurse at Christus Trinity Mother Frances, was convicted of capital murder last Tuesday after a three-week trial concluded that he killed at least four patients in a months-long murder spree between June 2017 and January 2018.
Prosecutors believe the former nurse is linked to six additional alleged victims.
Davis’ four victims—Chris Greenway, Joseph Kalina, John Lafferty, and Ronald Clark—were all healthy and resting in the ICU from heart surgery when they experienced seizure-like episodes but did not have seizures.
In an arrest warrant, heart doctors testified that all of them died in the same way, with one expert saying: “these patients were intentionally injected with air through their radial artery lines by William Davis. I can find no other logical explanation for the events described above.”
Davis was arrested in 2018 after hospital officials saw an “anomaly” of similar deaths, according to the warrant.
The prosecution, led by Smith County District Attorney Jacob Putman, has called scores of witnesses in the previous three weeks, ranging from family members of the victims to surgeons and nurses who treated the victims.
Tiffany Farmacka, Clark’s daughter, claimed Davis murdered her entire family, claiming she lost her brother to sadness and her mother became “just a shell of what she was.”
“We don’t trust anybody as much as we do the people at the hospital. It’s when we’re at our most vulnerable… Nobody could imagine someone being that evil, “Putnam said last week.
Investigators also played two phone calls Davis made from jail just hours before the verdict during the sentencing phase.
Davis acknowledged to his ex-wife over the phone that he tried to prolong the patients’ stay in the ICU so he could work longer shifts to make more money. In another, he and his brother chastised the jury for not deliberating for a longer period of time, demonstrating little remorse for his conduct.
“It’s hard enough to hear about it. But you don’t have to live it. It wasn’t your parent that was murdered As hard as it was for you to hear about it, it wasn’t hard for him to do it,” Putman told the jury on Wednesday.
Davis’ case will be automatically appealed to the Texas Court of Criminal Appeals.
