Authorities say Dennis Barber and Matthew Bills escaped from a Drug and Alcohol Rehabilitation Program in Decatur after being transferred from the Ouachita River Correctional Unit.
The two men were spotted on John Brown University's campus April 16, where they told a faculty member they were looking to enroll.
The JBU employee thought the situation seemed strange and called campus security.
When security confronted the men, they ran into the woods, but Siloam Springs police officers were able to track down and arrest Bills.
But according to the Arkansas Department of Community Correction, Dennis Barber, serving time for a drug charge, is still on the run.
