An agreement Wednesday by a former Walker County jailer to plead guilty to charges related to the 2023 death of inmate Tony Mitchell revealed horrific details about Mitchell’s final days.

Joshua Conner Jones this week signed an agreement to plead guilty to involuntary manslaughter involving reckless conduct in Mitchell’s death. Jones faces up to life in prison.

At an arraignment on Aug. 15, a federal judge will set a date to accept Jones’ plea.

Here are some of the things we learned as a result of that plea agreement:

A criminal investigation is underway:

Mitchell’s mother, Margaret Mitchell, filed a federal civil lawsuit claiming that deputies tased Mitchell and caused his death through abuse and medical neglect at the hands of Sheriff Nick Smith and staff at the jail, including corrections officers, nurses and an investigator.

However, it had never been made public that federal officials were conducting a criminal investigation into Mitchell’s death.

Now, it appears other individuals could be charged in the case. Who that might be and what charges they could face are not yet known.

The Walker County Sheriff’s Office had no comment when asked about Jones’ plea agreement.

In addition to the plea in Mitchell’s death, Jones also pleaded guilty this week to hitting another inmate in 2022 in the face with a can of O.C. spray so hard that Jones broke the can and dispersed the spray in the cell.

The inmate had complained about being in a cell with two others. An investigation found no force was necessary and that Jones and an unidentified officer wrote false reports stating the inmate advanced on them.

Mitchell was abused in retaliation for shooting at deputies:

Mitchell died Jan. 26, 2023 at Walker Baptist Medical Center, just over two weeks after he was arrested on charges that he shot at deputies during a welfare check requested by his family.

On the day he was arrested, Mitchell covered himself in black spray paint and claimed to have a “portal to hell.”

It was initially claimed Mitchell was placed in a freezer at the jail. The plea agreement, however, states Mitchell was put in a “notoriously cold” cell with no sink, toilet, or running water.

When Mitchell was booked, he could not walk, was disoriented, non-combative and could not follow directions. Officers “wrapped a suicide smock around him.”

Jones said Mitchell never received any medical evaluation until the morning of his death, two weeks later.

Corrections officers repeatedly chose not help him and would dismiss his needs by saying, “(Expletive) him, he gets what he gets since he shot at cops, or words to that effect,’’ the document states.

“Jones (and the other jailers) spoke directly to (Mitchell) saying that he was now in their ‘house’ and that he had to deal with them,’’ records show.

On Jan. 26, 2023, one of the unnamed officers told Jones that a nurse had ordered that Mitchell be taken to a hospital or he might die.

One of the co-conspirators replied, “I’ll tell you what, next time you’re on the toilet taking a (expletive), I’ll call you to bother you with something unimportant.”

The officers also repeatedly made comments that Mitchell “should have been killed because he shot at deputies rather than being brough to the jail,’’ the document says.

Jailers lied about Mitchell’s condition as he lay dying:

Jones said he watched Mitchell deteriorate over the two weeks after his Jan. 12, 2023 arrest.

“At the time he passed, (Mitchell) was almost always naked, wet, cold, and covered in feces while lying on the cement floor without a mat or blanket,’’ the records state.

By the second week of being jailed, Mitchell was largely listless and mostly unresponsive to questions.

The agreement states Jones and the co-conspirators denied Mitchell medical care by falsely telling medical staff that Mitchell was too combative to be evaluated “when in truth that was not the case.”

The efforts to deny Mitchell medical and mental health care persisted even though he was frequently talking incoherently about “demons.”

“Calling (Mitchell) combative was an excuse to mistreat him,’’ documents state. “There was no conduct that could have been committed by (Mitchell) that would have justified the denial of medical access.”

Mitchell was finally taken to the hospital — in a patrol car:

According to Jones, jail supervisors on Jan. 26, 2023 failed to arrange for Mitchell to go to the hospital for more than three hours after the nurse’s instructions.

Jones, after he took detainees to court, joined others at Walker Baptist Medical Center Hospital where Mitchell had been taken in the back of a patrol car rather than an ambulance.

When Jones arrived, he learned Mitchell’s mother had been called to the emergency room and overheard her giving permission to remove Mitchell from life support.
