Florida Charges Isabelle Johnson, 38, With Murder as 3 Others Are Arrested

Q: What secret relationship led to a Florida man's murder and a desperate, multi-state manhunt?

There is no confirmed public evidence of a “secret relationship” behind Jason Christopher Coulthart’s killing. Based on the sheriff’s office statements and the additional reporting, authorities have said only that the case appears “domestic in nature” and that the people involved knew one another. They have not disclosed the exact relationship between Coulthart and Isabelle Johnson, the 38-year-old woman wanted on a murder charge, nor have they announced a motive or cause of death. What is established is that Coulthart, 43, was reported missing in May and his remains were found June 25 in a shallow grave on a Freeport property in Florida’s Panhandle. Johnson is accused in the killing and is the focus of an active, multi-state manhunt. Investigators say she has ties to Florida and Georgia and may be using several aliases, including Harley, Jessica Elaine Bowman, Jessica Elaine Thrush, and Jessica Dowdy. Authorities have also arrested multiple people accused of helping her evade capture, including Michael Ray White, Kathleen Morris, Martin Leaverton, Sandra Leaverton, and Bobbi Wagstaff. Investigators allege they provided transportation, shelter, supplies, a phone, or other assistance after Coulthart’s body was discovered. So the most accurate answer is that the relationship at the center of the case has not been publicly revealed. Officials have described it only as a domestic, known-parties matter, while the motive remains undisclosed.

Walton County authorities said 38-year-old Isabelle Johnson is actively evading arrest after being charged with murdering 43-year-old Jason Christopher Coulthart, whose remains were found in a shallow grave in Freeport.
Coulthart was last seen May 24 leaving the College Condominiums, and investigators recovered his body on June 25 after developing leads from his missing-person case.
Authorities say Johnson may be using aliases including Harley, Jessica Elaine Bowman, Jessica Elaine Thrush and Jessica Dowdy, and may have changed her appearance since surveillance footage captured her inside a business last month.
Three people have already been arrested in the case, including Michael Ray White, 74, and Kathleen Morris, 59, who investigators say helped Johnson with hiding, transportation, supplies and misleading police.
Sheriff Michael Adkinson warned that anyone still helping Johnson avoid arrest will face charges as the homicide investigation continues.
