Monday 4 p.m. Two inmates Dylan Ray Three Irons and Prime Tounwin Brown have been captured less than 20 miles from the jail. The two other inmates are still missing.

The search is on for four Oklahoma detainees who escaped through the plumbing system Sunday morning.

In a statement, the Caddo County Sheriff said four inmates escaped through a trap door above the shower, then crawled through a pipe to the pipe chase door to freedom.

Authorities are searching for Dylan Ray Three Irons, Prime Tounwin Brown, Anthony James Mendonca and Triston Cheadle.

When guards did a headcount, they found there were four inmates missing. Witnesses reported seeing men on the street in standard-isssue oranges prison uniforms.

There were about 200 inmates in the facility Sunday morning, overseen by three guards.

Mendonca, who also goes by aliases Thomas Jink and Thomas Wesley Johnson, was being held on escape charges.
