A former police chief who is also a convicted killer and rapist nicknamed the “Devil in the Ozarks” was captured by law enforcement 1.5 miles north-west of the prison he escaped from following a 13-day manhunt in the mountains of northern Arkansas, authorities announced on Friday.

Grant Hardin’s identity was confirmed through fingerprinting, the Izard county sheriff’s office said in a Facebook post.

Hardin, a former police chief in the small town of Gateway near the Arkansas-Missouri border, was serving lengthy sentences for murder and rape. Eventually, his notoriety led to a TV documentary, 2023’s Devil in the Ozarks.

Hardin had been held at the Calico Rock prison since 2017 after pleading guilty to first-degree murder in a fatal shooting. In order to escape, he had impersonated a corrections officer “in dress and manner”, according to a court document. A prison officer in one of the guard towers opened a secure gate, allowing him to walk out of the facility.

Rand Champion, a spokesperson for the state prison system, said that someone should have checked Hardin’s identity before he was allowed to leave, describing the lack of verification as a “lapse” that’s being investigated.

Searchers had been using bloodhounds, officers on horseback, drones and helicopters in their hunt for Hardin since he escaped on 25 May.

An elite and highly trained US border patrol team had recently joined the search, federal authorities announced this week.

The border patrol tactical team known as BORTAC provided “advanced search capabilities and operational support” in the hunt for Hardin, US customs and border protection said. Its members are experienced in navigating complex terrain, the agency said.

The Ozark mountains region is known for its rocky and rugged landscape, thick forests and an extensive cave network.

Hardin pleaded guilty in 2017 to first-degree murder for the killing of James Appleton, 59. Appleton worked for the Gateway water department when he was shot in the head on 23 February 2017, near Garfield. Police found Appleton’s body inside a car. Hardin was sentenced to 30 years in prison.

Hardin’s DNA was also matched to the 1997 rape of a teacher at an elementary school in Rogers, north of Fayetteville. He was sentenced to 50 years for that crime.
