The Miller County Sheriff's Office says 23-year-old Cortez Hooper and 36-year-old Quincy Stewart were still at large Tuesday morning. The pair was discovered missing early Monday.
Authorities say the men jumped out a second-floor window then somehow got around a 10-foot fence topped with razor wire. Chief Deputy Duke Schofield tells the Texarkana Gazette that an investigation is under way to determine how the men obtained the hacksaw blade.
Both men were being held on murder charges.
The escape is the first since Sheriff Ron Stovall took office in 2009. In 2008, more than a dozen inmates escaped in separate instances.
