A woman accused of murder is on the run after the remains of a missing man were discovered in a shallow grave.
Isabelle Johnson, 38, is wanted on an open count of murder and is believed to be actively evading law enforcement following the discovery of human remains belonging to Jason Christopher Coulthart, 43.
Police released footage of Johnson from a business, showing her in the days after investigators say Coulthart’s remains were found.

Authorities warned she may have changed her appearance since the video was recorded, but said the footage could help members of the public recognise her and identify her voice.
Coulthart, who was reported missing on 24 May, 2026, was last seen leaving the College Condominiums on East College Boulevard in Niceville, Florida.
At the time he disappeared, the 5ft 8in man was described as wearing an unknown-coloured polo shirt, khaki shorts and Nike shoes.
His disappearance initially sparked a missing person investigation before police later confirmed human remains found in Freeport had been identified as belonging to Coulthart.
Johnson is now wanted in connection with his death and police have urged anyone with information about her whereabouts to contact investigators.
Authorities said Johnson was last seen in Destin, Florida and is believed to have been avoiding capture.

The Walton County Sheriff’s Office warned members of the public not to approach her if spotted and instead to contact law enforcement.
The investigation into Coulthart’s death remains ongoing as detectives work to establish the circumstances surrounding his disappearance and death.
Police have not released further details about what led investigators to Johnson or a possible motive.
Anyone with information about Johnson’s location or details about the case is urged to contact the Walton County Sheriff’s Office.
