Isabelle Johnson, a suspect in a murder case who authorities claim used multiple disguises and identities to evade capture, has been arrested. The Walton County Sheriff’s Office announced her apprehension late Thursday.

Johnson, 38, is charged with the murder of 43-year-old Jason Christopher Coulthart. Coulthart was found dead in a shallow grave in Florida in June, having gone missing in May. Investigators have described Johnson as a "master manipulator" for her alleged use of various identities to elude law enforcement.

Coulthart was reported missing on May 24, last seen leaving the College Condominiums complex in Florida, according to the sheriff's office. Unidentified remains were discovered on a property in Freeport, Florida, on June 25, after investigators determined where Coulthart's body had been buried. A DNA match in July confirmed the remains belonged to Coulthart.

In connection with Coulthart's murder, five other individuals have also been arrested and charged. Two of these individuals are accused of assisting Johnson in evading investigators, the sheriff's office stated.
