Nearly a week after a prisoner who was featured in a documentary telling the story of a murder and rape he committed escaped from an Arkansas Prison, the search for Grant Matthew Hardin continues.

The Federal Bureau of Investigation announced on Friday that they have upped the reward to $20,000 for information on his whereabouts. 

Hardin escaped from the North Central Unit Prison at Calico Rock in North Central, Arkansas on Sunday May 25. He escaped the minimum security facility by wearing make-shift clothing that looked like a law enforcement uniform. In an updated release from the FBI, the state that Hardin is considered armed and dangerous and say their agency is joining the U.S. Marshal Service, the Arkansas Department of Corrections, and the Arkansas State Police in the search. 

The release also states that Hardin does have ties to communities in the Lakes Region including Eureka Springs and Holiday Island in Carroll County as well as Huntsville in Madison County. 

Hardin has been in prison since 2017 for the murder of a man in Gateway, a community in northern Benton County just south of the boarder with Barry County in Missouri. His DNA collected at the time of the murder led to him being linked to the rape of a school teacher in Rogers in 1997. 

Hardin has a background in law enforcement having served for a time as Police Chief in Gateway in 2016 with other media reports indicating Hardin spent some time as a member of the Eureka Springs Police Department in the 1990s.

A documentary, "Devil in the Ozarks" was released by Max in 2023 detailing the two crimes and the events that led to Hardin's capture.
