Taylor, Texas (KLTV)-A former Taylor nurse was sentenced to inject air into the patient’s blood. The second day of his sentence has already begun.

William Davis, 37, from Hallsville, was convicted of murder. The jury is hearing testimony to determine whether he will be sentenced to death or life imprisonment.

1:53 PM -The next witness is Jamie Turner, an investigator at the Taylor Police Department.

He said that on March 27, 2018, the police executed a search warrant at Davis’s home in Halsville. The police took some items (without specifying or showing what they were) back to the police station.

The next witness, Chris Ledbetter, is a former agent of the Texas Department of Public Safety.

Ledbetter discussed the process of extracting data from the phone after executing a search warrant.

After extracting Davis’ search history from his mobile phone, it showed that the mobile phone visited multiple discussion bubble websites.

The next witness is Agent John Day, who is an agent of the U.S. Secret Service.

He said that Taylor police contacted them to process and inspect two laptops, two mobile phones and two USB flash drives.

He said that the Internet search history of one of Davis’s laptops showed that he researched “a list of serial killers by the number of victims” and searched whether Francis’s mother was investigating serial killers.

Judge Jackson said they may end the sentencing phase in the middle of next week.

11:28 am -In the case of Mr. Sanders, Yarbrough said that his review of his medical records revealed that someone had deliberately injected him with insulin. He said that in his opinion, this was the cause of his death.

Yarbrough said all 12 patient incidents were the result of deliberate injections.

10:57 am -In the case of James Blanks, Dr. Yarbrough stated that he suffered a major incident on January 6, 2017. He underwent heart surgery on January 5, 2017. Similar to Perry Frank, Yarbrough said that his review led him to the conclusion that air was injected into the venous system of Blanks, causing his death.

10:29 am -The next witness is Wendy Stone, a former nurse of CHRISTUS.

On June 15, 2017, she was the head nurse on the CVICU floor. Stone said William Davis called her to Sanders’ room because Sanders’ blood sugar level was very low after midnight on the 15th. When she arrived in the room, she said that William Davis tried to get Sanders to respond. Sanders didn’t breathe, and they started chest compressions.

The next witness is Wyley McCoy, the former pharmacy director of CHRISTUS Mother Frances.

In June 2017, Teresa Meeks asked McCoy to review Sanders’ insulin bag. At about 1:00 in the morning, McCoy said that Sanders’ blood sugar levels had dropped to dangerous levels. It dropped from 140 to 23. He said this may be due to the rapid increase in insulin injected into the pump.

Pump records show that this is not the case in Sanders’ case. Another option is to inject insulin. (Does not pass the pump)

The next witness is Dr. William Yabreu, a lung specialist at Virginia Hospital in Dallas. He served as an expert witness for the prosecution and has no relationship with CHRISTUS.

In James Wages’ case, he said that his review of the records led him to conclude that on August 7, 2017, air was injected into Wages’ arteries.

Take the 57-year-old Mr. Glenn as an example. Aberle said he had risk factors such as diabetes before the operation.

In reviewing Glenn’s medical records, Yarbrough said that Glenn injected air into his arteries on October 26, 2017.

In the case of 58-year-old Gary Parker, Yarbrough said he had a major incident on July 14, 2017. He showed signs of seizures during the event. Yarbrough said that after reviewing Parker’s medical records, he concluded that air was deliberately injected into his arteries.

In the case of Perry Frank, Yarbrough said that Frank is different. He said that the other victims had air injected into their arteries, but in Frank’s case, air was injected into the veins.

Yarbrough said Frank’s death was caused by the injection of large amounts of air into the venous system, not the arterial system.

9:31 am -In the case of Rickie Glenn, Dr. Caccitolo said that he also did well after the operation. He received another early morning call saying that he had crashed. He said that the patient’s car accident caused a lot of anxiety and trust issues between doctors and nurses. Dr. Caccitolo’s defense had no problems.

The next witness is James Sanders’ granddaughter Amirandrum.

She said that her grandfather was a veteran who was influential in the community and was friendly to everyone. His operation was on June 13, 2017.

Landrum said he did “very well” after the operation. She said that she received a call in the early morning of June 14, 2017, saying that he had already “coded”. On the 16th, Sanders lost his life support.

Landrum’s defense is no problem.

9:20 am- Dr. James Caccitolo was the first witness of the day. He is a cardiovascular surgeon at CHRISTUS Mother Frances. In Perry Frank’s case, Caccitolo is his surgeon. Caccitolo said that Frank had recovered well from the heart operation, but received a call from the nurse early in the morning. The nurse said that Frank’s condition had worsened. Frank died in the hospital on June 22, 2017. Caccitolo said that it is not common to order an autopsy after death in a hospital, but he ordered an autopsy here. Caccitolo also testified that James Wages crashed unexpectedly on August 7, 2017. Caccitolo is also his heart surgery. Caccitolo said they sought an external review to help explain the cause of the crash for all patients. But in August 2017, Caccitolo stated that they are well aware of this trend.
