An inmate being held in the Buchanan County Jail died early Thursday morning.

According to the Sheriffs Office 57-year-old Steven Criswell was found unresponsive during a routine cell check at 12:25 a.m.

“At this time we believe it to be some form of a natural cause,” said Deputy Sarah Hardin, Public Information Officer with the sheriff’s office.

Hardin said the Buchanan County Ambulance service provided medical care but was unable to revive Criswell.

“At this time we believe it to be some form of a natural cause but we will still go through the regular investigation and autopsy like we would any death,” said Hardin.

“He was actually just sentenced to DOC for stealing,” Hardin said.  “Usually when an inmate is sentenced to the Department of Corrections they will return to the Buchanan County Jail until a travel order comes over to the courthouse from the judge.”

According to online court documents Criswell was sentenced in court Monday.

He had entered a guilty plea in Judge Patrick Robb’s court for felony stealing, his third offense.

Hardin said she believes his travel papers were set to arrive this morning to serve a 2-year sentence in the DOC.

It’s the second death that has taken place in the Buchanan County Jail this year.

46-year-old Roger Pankau died in Buchanan County jail two months ago.

Pankau was also found unresponsive during a routine cell check.
