$11K reward offered for info leading to arrest of Walton County murder suspect

WALTON COUNTY, Fla. (WTVY) - A new push is being made, including an $11,000 reward, to locate a woman with ties to Houston County and other areas of Florida, Georgia and lower Alabama that is being sought by law enforcement in connection with the death of a man in Walton County, Florida.

38-year-old Isabelle Rose Johnson is wanted on an open count of murder in the killing of Jason Coulthart.

Johnson described as a being about 5′3″ tall, around 120 pounds, with brown hair and hazel eyes, though investigators believe she may have dyed or cut her hair to help with disguising herself.

She is also believed to have a floral tattoo on her left hand near her thumb and forefinger, as well as a tattoo on her right ankle.

Additionally, Johnson is known to use multiple identities and aliases, including:

• Harley
• Jessica Elaine Bowman
• Jessica Elaine Thrush
• Jessica Elaine Thrash
• Jessica Dowdy
• “Denise”

Johnson is known to frequent the Houston County area, and is known to manipulate individuals to provide her with transportation, money and other assistance using sympathetic narratives such as describing hardships that include a history with domestic violence.

Coulthart, 43 of Niceville, was reported missing back in May, and following an extensive investigation, on June 25 detectives were able to locate his remains buried in a shallow grave on a property off Sunset Lane in Freeport.

In the wake of this discovery, Johnson was quickly identified as a suspect of interest in the case, and a warrant for her arrest was issued. Since then, Johnson has managed to avoid capture thanks to the help of others, and remains at-large at this time.

Thus far, five individuals have been arrested for accessory after the fact to a capital felony, along with other individual charges mostly unrelated to the case. Those arrested include:

• Bobbi Wagstaff, 31 of Freeport
• Martin Leaverton, 63 of Fort Walton Beach
• Sandra Leaverton, 63 of Fort Walton Beach
• Michael Ray White, 74 of Santa Rosa Beach
• Kathleen Morris, 59 of Santa Rosa Beach

Currently, $11,000 in total reward is being offered for information that leads to locating and capturing Johnson: $6,000 by Emerald Coast Crime Stoppers and another $5,000 by the Florida Sheriffs Association Criminal Apprehension Assistance Program.

Anyone with information regarding Johnson’s whereabouts or other details related to the case are asked to contact the Houston County Sheriff’s Office at (334) 677-4808, the Walton County Sheriff’s Office at (850) 892-8111.
