A Texas jury sentenced a former homicidal nurse to death on Wednesday for the murder of four patients after undergoing heart surgery.
William George Davis, 37, was convicted of capital murder by the same Smith County jury a week earlier for injecting air into the arteries of patients and causing severe brain damage and death.
Davis, of Hallsville, killed all four patients at Tyler’s Christus Trinity Mother Frances Hospital in 2017 and 2018.
During sentencing, prosecutors called Davis a “serial killer” and interpreted for jurors a taped phone call he made to his ex-wife from prison after the October 19 verdict. .
He confessed that he tried to keep his patients in the cardiac intensive care unit as long as possible so he could rack up more overtime and extra pay.
The plot was exposed after its victims John Lafferty, Ronald Clark, Christopher Greenway and Joseph Kalina suffered from unexplained neurological issues while recovering from surgery and then died.

All four victims were in stable condition after their operations before suffering from stroke-like symptoms, testimony at trial said.
The CT scans showed that they had air in the brain from the injections.
Davis’ defense attorney argued his client was innocent and was only charged because he was present when the patients died.
