Marie Moore

In 1988, Marie Moore, a Multiple [Personality Disorder] in N.J. ran a 
coven which tortured teenagers. The police found a well hidden body in 
her house, but the corrupt judicial system did not convict her of murder.

Dorothy Lewis, M.D., a psychiatrist in New York and an expert on causes of 
violence, thought dissociative identity disorder was a figment of someone's 
overactive imagination until she witnessed Marie Moore, accused of murdering 
an adolescent in New Jersey, switch to her male alternate personality Billy 
while interviewing her in 1984.
