A massive manhunt is underway in the Florida Panhandle after investigators discovered a missing man's body buried in a shallow grave. Five people are tied to the homicide investigation, but the primary suspect remains at large. 

The Walton County Sheriff's Office confirmed that the human remains belong to Jason Christopher Coulthart, 43, who vanished on May 24. 

Freeport property grave

What we know:

Detectives received a tip on June 25 that Coulthart was buried on a property off Sunset Lane in Freeport. Deputies executed a search warrant the same day and uncovered a body in a shallow grave. 

Forensics positively identified the body as Coulthart last week. He was last seen leaving the College Condominiums on East College Boulevard.

Deputies arrested Michael Ray White, 74, and Kathleen Morris, 59, of Santa Rosa Beach, on July 10. Both face charges of accessory to a capital felony after the fact and obstruction. 

Investigators say White hid Johnson at his home between June 25 and June 30. White provided supplies and helped coordinate moving Johnson to a second location. 

Morris lives at the same address and admitted to transporting Johnson, giving her supplies and lying to deputies. Authorities recovered incriminating text messages from her cellphone. 

According to the Walton County Sheriff's Office, witnesses confirmed that Martin and Sandra Leaverton also helped shelter Johnson. 

The Leavertons allegedly retrieved Johnson’s belongings and tried to find her out-of-state refuge. They remain held at the Walton County Jail on accessory after the fact to capital murder charges.

"Anyone found to have helped or is still assisting Isabelle Johnson avoid arrest will be charged accordingly," Sheriff Michael Adkinson said. "If you give her a place to stay, help her hide, or lie for her, you will face consequences. This is a homicide case. We will not allow anyone to get in the way of this investigation."
