TYLER, TX (KLTV) - Newly released indictments allege a Tyler nurse killed three patients and injured three others.

William George Davis, 34, of Hallsville, is currently under indictment for one charge of capital murder, one charge of first-degree murder and five charges of first-degree aggravated assault.

The capital murder indictment lists the following victims:

  • John Lafferty on June 16, 2017
  • Ronald Clark on July 26, 2017
  • Christopher Greenaway on Aug. 4, 2017

The charges stem from allegations that Davis caused death or harm by intentionally introducing air into the arterial systems of patients, Smith County District Attorney Matt Bingham said in June after the initial indictments.

Davis was arrested back in April after a lengthy investigation. Bingham said hospital officials alerted his office and law enforcement and the hospital's remained compliant throughout the investigation.

Davis was a registered nurse at CHRISTUS Mother Frances Hospital in Tyler. Law enforcement is investigating allegations that Davis tampered with at least three patients at the Louis and Peaches Owen Heart Hospital in Tyler. Davis allegedly injected air into the arterial lines of at least seven patients at the hospital, officials say. Two of those patients died and two others were left in a vegetative state.

Davis' original indictments name victims Greenaway, Pamela Henderson and Joseph Kalina.

The new aggravated assault indictments list the following additional victims:

  • Gary Parker on July 14, 2017
  • James Wages on Aug. 7, 2017
  • Rickie Glenn on Oct. 26, 2017

An arrest affidavit alleged officials discovered disturbances in patients' arterial line waveforms matched up with his presence in the hospital room. An arterial line is a thin catheter inserted into an artery.

As of June 29, a trial date had been set for Davis. According to judicial records, a jury trial is scheduled for Dec. 3 with Judge Christi Kennedy presiding.
