A Texas nurse was found guilty of four patients’ murders back in 2017 and 2018 and is now facing the death penalty when the sentencing phase of his trial begins today.
It did not take more than an hour for jurors to convict William George Davis of killing John Lafferty, Ronald Clark, Christopher Greenway, and Joseph Kalina, as they layed recovering from critical heart surgeries at the Christus Mother Frances Hospital in Tyler.
The jury’s verdict seemed evident after the testimony of Dr. William Yarbrough, a Dallas-area pulmonologist, who explained that the four men sustained brain damage after getting air injection into their brain arteries.
The damage, Yarbrough said, had nothing to do with blood pressure or underlying health issues; something the expert added he had never seen in his decades as a doctor.
Davis’ defense was to put the blame on the hospital’s procedures and depict the former nurse as a “scapegoat” but prosecutors argued that since Davis left no such incidents occurred again and that he “liked to kill people.”
