An inmate from Deer Ridge Correctional Institution died unexpectedly Monday afternoon at a local hospital, the Oregon Department of Corrections announced Wednesday.

The department identified the inmate as John Derrick Stafford, 49. Stafford was taken to an area hospital Monday with medical issues and died at approximately 4:40 p.m.

A Corrections Department news release did not specify the hospital where Stafford was taken and a representative was not available for comment.

Oregon State Police criminal investigators found Stafford’s death was not related to a crime, the department reported.

Stafford entered custody March 22, 2011, to serve a sentence for one count of first-degree burglary out of Marion County, according to the department. His earliest release date was Dec. 27, 2015.

Deer Ridge, a minimum-custody facility in Madras, houses approximately 756 inmates who are within four years of release.
