TYLER, Texas (AP) — A Texas nurse was convicted Tuesday of money murder in the fatalities of four sufferers who died just after prosecutors say he injected them with air pursuing heart surgical procedures.

The Smith County jury deliberated for about an hour prior to locating William George Davis, of Hallsville, guilty of capital murder involving multiple victims. Prosecutors planned to look for the loss of life penalty for the duration of the sentencing stage, which was scheduled to start Wednesday.

Davis, 37, was accused of injecting air into the 4 patients’ arteries following they underwent heart surgery at the Christus Trinity Mother Frances Medical center in Tyler in 2017 and 2018. For the duration of restoration from their surgical procedures, the 4 — John Lafferty, Ronald Clark, Christopher Greenway and Joseph Kalina — suffered unexplained neurological complications and died.

Through the demo, Dr. William Yarbrough, a Dallas-area pulmonologist and professor of interior drugs, defined to the jury how injecting air into the arterial process of the brain results in mind damage and death.

Yarbrough claimed he was capable to determine there was air in the arterial system of the victims’ brains by viewing visuals from mind scans — anything he said he experienced by no means just before noticed in his a long time in drugs.

He ruled out blood tension complications or any other leads to of dying in addition to the injection of air, and stated it should have occurred following the surgical procedures for the reason that the troubles occurred when the sufferers have been in restoration.

Protection lawyer Phillip Hayes explained to the jury that the medical center experienced concerns and that Davis was a scapegoat who was only billed for the reason that he was there when the deaths occurred.

Prosecutor Chris Gatewood claimed in the course of closing arguments that Davis “appreciated to kill persons.” And prosecutor Jacob Putman stated the healthcare facility hadn’t modified any of its techniques and hadn’t experienced any comparable incidents because Davis still left.
