Texas prison inmate charged with murder after allegedly attacking detention officer: ‘Pure evil’

A 28-year-old detention officer in Texas is dead after he was allegedly attacked by an inmate while returning the inmate to his cell.

During a press conference on Tuesday Ellis County Sheriff Brad Norman revealed that Officer Isaiah Bias was killed Monday during the alleged attack on the prison.

“It is with great sadness that we stand here today and acknowledge the loss of one of our relatives. … Isaiah Bias, age 28, was a dedicated detention officer with more than six years of service with the Ellis County Sheriff’s Office,” Norman said.

Norman called 45-year-old suspect Aaron Thompson’s alleged attack “purely evil” but did not provide details about how Bias was killed.

“It was a heinous, horrific, premeditated murder that was senseless and unnecessary,” Norman said. “The final decision will be made by the prosecution as to whether or not to seek the death penalty in this case. If I have anything to say about this, then that is exactly what will happen, but the final decision lies with the prosecutor’s office.” “

According to an arrest warrant affidavit received from KDFWThompson punched Bias, knocked him to the ground and then allegedly began choking and hit him in the head with his fist, knee and foot.

The affidavit says Thompson then walked to a table and sat down, leaving Bias in a “large pool of blood.”

Thompson was sentenced to prison last month for three counts of assault on a public servant and avoid arrest and was in solitary confinement 23 hours a day, Norman said.

Norman said he met Bias as a teenager as part of the prison’s exploration program.

“He wanted to work in law enforcement. He came to work for the prison,” Norman said. “At 18 you can work in prison. In Texas you can’t become a peace officer until you’re 21,” Norman said.

Norman also described Bias as a “very family-oriented person” and said he had only become an uncle a week before his murder.
