Murder suspect captured following 45-day, 3-state manhunt after victim discovered in shallow grave

Murder suspect Isabelle Johnson was arrested Thursday following a weeks-long multistate manhunt spanning Florida, Georgia and Alabama, authorities said.

A U.S.

Marshals task force arrested Johnson, 38, at a home in Cottondale, about an hour west of Tallahassee, according to the Walton County Sheriff's Office.

She was wanted on a murder charge in the death of Jason Coulthart, whose body was found buried in a shallow grave in Florida on June 25.

Authorities said Johnson was taken into custody without incident Thursday afternoon, capping a 45-day manhunt.

She was booked into the Jackson County Jail and is expected to be extradited to Walton County.

Officials said she could face additional charges.

"Isabelle Johnson is in custody." Officials said the arrest stemmed from information developed by the Walton County Sheriff's Office Cyber Crimes Unit about Johnson's whereabouts.

Jackson County Sheriff Donald Edenfield said that after receiving the information, his deputies and members of the task force responded to an address off Peanut Road, just outside Cottondale.

Walton County Sheriff's Office Chief Deputy Dustin Cosson praised the cooperation among local, state and federal law enforcement agencies that led to Johnson's arrest.
