Newly released arrest reports detail how a network of suspected accomplices allegedly helped a wanted fugitive hide a body and hide from law enforcement.
These alleged accomplices are accused of helping deputy-dubbed “master manipulator” Isabelle Rose Johnson, 38, steer clear of cops; she’s been on the run for several weeks.
Johnson, of Florida, is accused of killing Jason Coulthart, 43, whose body was found buried in a shallow grave on a Florida property on June 25. He was last seen alive on May 24.

Johnson’s possible motive for the alleged murder? The report says the witness told investigators “he was aware of her ‘getting rid’ of a boy because he was ‘aggravating and irritating her.'”

This witness also said that “the ‘boy’ was also threatening to interfere with Isabelle’s custody of her children.”
Wagstaff is charged with accessory after the fact to first-degree murder and possession of methamphetamine.
