Texas Nurse Found Guilty of Murdering Four Heart Surgery Patients by Injecting Air into Their Arterial Lines While They Were in Recovery

A Texas nurse murdered four heart operation patients who had just gotten out of their surgeries.

On Tuesday, 37-year-old William George Davis was convicted of capital murder for killing four patients by injecting air into their arterial lines while they were recovering from heart surgery Tyler’s Christus Trinity Mother Frances Hospital, People reports. Davis was an employee at the hospital until he was fired in 2018.

The incidents happened in 2017 and 2018, when Davis injected the air in their arterial lines, leading to brain damage. According to his arrest affidavit, Davis was seen several times through surveillance going into the rooms of patients who were healing from heart operations. Davis took the lives of John Lafferty, Ronald Clark, Christopher Greenaway and Joseph Kalina.

During the jury’s deliberations, prosecutor Chris Gatewood said Davis’ motive was “simple: He likes to kill people. He enjoyed going into the rooms and injecting them with air. If you watch the video on Kalina, he set at the end of the hall and he watched those monitors and he waited. That’s because he liked it.”

The New York Times reports prosecutors were seeking the death penalty as Davis’ punishment. “It turns out a hospital is the perfect place for a serial killer to hide,” the district attorney for Smith County, Jacob Putman, during the trial.
