Authorities in Walton County, Florida, have intensified their search for Isabelle Johnson, a 38-year-old woman wanted on an open count of murder. The Walton County Sheriff’s Office (WCSO) is offering a reward of at least $16,000 for information that leads to her arrest and the resolution of the case involving Jason Christopher Coulthart, 43. Officials warn that Johnson is actively evading capture by using fake identities and frequently altering her physical appearance.
Discovery of Remains in Freeport
The investigation began after deputies discovered human remains buried at a property in Freeport on June 25, according to the Walton County Sheriff’s Office. The deceased has been identified as Jason Christopher Coulthart, who had been reported missing since May 24 when he was last seen leaving the College Condominiums. Investigators stated that tips gathered during an initial missing person inquiry directly led law enforcement to the burial site in Freeport.
Officials have not released a potential motive for the homicide or specific details regarding how Coulthart died. Additionally, police have not disclosed his exact relationship to Johnson. Niceville Chief of Police Mark Hayse addressed the community in a statement, noting that this is "not the news we hoped to deliver" and affirming support for Coulthart’s family.
Suspect Description and Known Aliases
Isabelle Rose Johnson is described as being 5 feet 3 inches tall and weighing approximately 120 pounds. She has brown hair, hazel eyes, and distinct tattoos, including a scorpion on her left thigh. Security footage captured Johnson inside a local business days after the body was unearthed, but detectives note she frequently changes how she looks to avoid detection.
Police have identified several known aliases used by Johnson, which include "Harley," "Jessica Elaine Bowman," "Jessica Elaine Thrush," "Jessica Elaine Thrash," "Jessica Dowdy," and "Denise." She has known ties to both Georgia and Alabama. Authorities emphasize that anyone who assists her in evading arrest will face severe criminal charges.
Charges Against Accomplices
The investigation has already resulted in the charging of five individuals with harboring or aiding Johnson. Among those named are Michael Ray White, 74, and Kathleen Morris, 9, both from Santa Rosa Beach. They were charged with accessory to a capital felony after the fact and obstruction.
Authorities allege that White assisted Johnson between June 25 and June 30. Meanwhile, Morris admitted to providing transportation and supplies while lying to deputies about Johnson’s whereabouts at her home. Walton County Sheriff Michael Adkinson stressed that anyone found helping or still assisting Johnson will be charged accordingly. Chief Deputy Dustin Cosson added that targeted enforcement is focused on identifying where she is hiding and holding those who help her accountable.
