William George Davis: The Serial Killer Nurse

Background

William George Davis, born on February 3, 1984, in Longview, Texas, was a nurse at Christus Trinity Mother Frances Hospital in Tyler, Texas. He was convicted of capital murder for killing four patients with air injections after they received heart surgery.

Crimes

From June 2017 to January 2018, multiple patients experienced unexplained complications after heart surgeries while in recovery. Davis was discovered after doctors observed air in the brains of patients on CT scans. Security footage captured Davis in the patients' rooms just before complications started. He was fired from his job as a nurse at the hospital a month before he was arrested in April 2018.
