No criminal charges will be filed in the death of an inmate at the Adams County Detention Facility, officials said Friday.

Tyler Tabor, who died of dehydration while in a medical wing at the Adams County jail, was determined to have died from “natural causes,” according to a 17th Judicial District Attorney news release.

Tabor, 25, was arrested three days before his death for heroin possession.

During his medical screening while being booked into jail, Tabor told authorities he used heroin on a daily basis, the release said. He was placed on an “opiate withdrawal protocol” and put in a medical unit.

The protocol required Tabor to receive medications, food and fluids and for officials to regularly take his vital signs, the release said.

Detectives investigating Tabor’s death were provided with video surveillance in the cell housing Tabor, but the release said it should be noted that the video recording system in the jail “is not performing as it should.”

The malfunction causes video to be broken up into clips that vary from seconds to minutes and lacks a time stamp, meaning “it is difficult to determine whether there are gaps in the recording.”

A chronology of events leading up to Tabor’s death provided by the district attorney’s office states that Tabor was taking his medication, sometimes eating and drinking, vomiting often and growing so weak that he was unable to stand. He fell over more than once.

At one point, a nurse had to give Tabor his medication because he could not hold it himself and a deputy had to help him sit on the floor so he would not fall over.

On the day before his death, a nurse who took Tabor’s vitals said Tabor asked about getting an IV, and he was told “not unless it’s absolutely necessary.”

About a half hour before Tabor’s death, deputies were supposed to check Tabor’s cell, but that check did not occur as deputies were “engaged in two other incidents,” the release said.

On May 17 at 5:25 a.m., a deputy observed Tabor lying in the middle of his cell moaning and talking incoherently.

Tabor was taken to be treated, where it was discovered that he was not breathing well.

Nurses tried to revive Tabor until paramedics arrived and pronounced him dead at 6 a.m.

On May 18, Dr. Michael Arnall, a forensic pathologist, performed Tabor’s autopsy and determined that Tabor died of dehydration and that the manner of death was natural.

“In summary, a review of the materials presented does not disclose any abuse, mistreatment or maltreatment that rises to a level of criminal culpability,” the release said. “The evidence demonstrates that … Mr. Tabor died as a result of his heroin addiction and dehydration associated with his withdrawal from the illegal use of that substance.”
