Ex-nurse sentenced to death for killing four patients by injecting them with air
CBSN
A former nurse in East Texas has been sentenced for killing four patients at a hospital in Tyler, Texas. William George Davis was found guilty of capital murder on October 19. On Wednesday, after about two hours of deliberation, a Smith County jury sentenced Davis to death, CBS affiliate KYTX reports.
Davis killed John Lafferty, Ronald Clark, Christopher Greenaway and Joseph Kalina at CHRISTUS Trinity Mother Frances Louis and Peaches Owen Heart Hospital by injecting air into their arterial systems.
In 2018, about a month before he was arrested, Davis looked at an article online: "List of serial killers by number of victims," a United States Secret Service special agent said during his trial.
