The Associated Press reports that a former Texas nurse has been charged with the murder of one of his patients. William George Davis was fired last month from the Texas hospital he worked for and is suspected in connection with the death of a patient that occurred last year.

In addition, six other patients treated by Davis were injured under his care. He will likely face aggravated assault charges for those cases.

Two of the six other patients suffered injuries that caused them to become vegetative.

In March of this year, the Texas Board of Nursing suspended Davis’ license after it was determined that he entered three patients’ rooms at the Louis and Peaches Owen Heart Hospital and performed some type of treatment that resulted in one death and two critical injuries.

Davis, 34, is being held on a $2 million bond for the murder charge. There is no attorney listed on his behalf in court records at this time.

According to the Boston Herald, Davis may also be suspected in a second patient death. One patient died in August – Christopher Greenaway, 47 – after having surgery and experiencing an “unexpected neurological incident” the following day.

The two patients left in a vegetative state are a 58-year-old man and 63-year-old woman.

The hospital that employed Davis says he has worked for them since 2013 and formerly worked for another hospital for two years.
