Defense witness Carolyn Murphy, a forensic psychologist said, “(He believes) he transforms into a werewolf,” and “holds the spirit of the wolf.”
The first record of Andrews believing he was a werewolf, she said, dates to 1996, though she suspects he had that same delusion during his first psychotic episode three years earlier.
Murphy said Andrews believed the voice of God commanded him to kill Barga-Milbury, whom he believed was a vampire.
In 2009 Andrew became convinced that another one of his neighbors was a vampire:
Andrews believed a different neighbor was a vampire. Andrews left mounds of dirt and flour on that neighbor’s door and once pounded on the neighbor’s door, calling her a “bitch,” though she didn’t answer.
At his home, according to police reports, police found two lists of names, several marked “hate with death.”
As to why Andrews didn’t kill this particular vampire neighbor “God didn’t tell him to kill her” Murphy said.
Mark Andrews has believed himself to be a werewolf for the past 20 years. During the time of the murder, Andrews was apparently not taking his medication.
