Capital murder trial begins for Texas nurse accused of killing 4 patients

A capital murder trial began Tuesday for a nurse accused of killing four patients at an East Texas hospital in 2017.

William Davis, 37, allegedly killed four men who had been recovering from heart surgery at Christus Trinity Mother Frances Hospital in Tyler by injecting air into their arteries, prosecutors allege.

“No one expects this is going to happen to them — certainly not in a hospital,” Smith County District Attorney Jacob Putnam told jurors during opening statements.
