Florida authorities are continuing a month-long search for Isabelle Johnson, 38, who is wanted in connection with the killing of a man found buried in a shallow grave. The Walton County Sheriff’s Office has released further identifying information, saying she may have altered her hair and overall appearance to avoid detection.

The sheriff’s office has highlighted Johnson’s tattoos and other distinguishing marks in the hope that members of the public can recognise her despite any alleged disguises. The case concerns the death of Jason Coulson, and investigators have warned that the suspect may have received help while evading arrest.
