Walt Bannerman (Chris Bruno) was Sarah's husband and the Sheriff of Penobscot County, Maine. Walt frequently called on Johnny and his psychic abilities to assist in investigations. Although painfully aware of Johnny's long and deep-running relationship with Sarah, Walt came to respect and befriend him while, at the same time, fearing the consequences Johnny might have on his marriage and his relationship with J.J. Even as Johnny and Walt became close friends, Johnny was still unable to prevent Walt's death after the vision came to him. In an attempt to rescue Gene Purdy from a burning building, Walt was trapped by flaming debris and killed.
