Crystal Gail Mangum has a long history of mental problems and has been diagnosed with a bi-polar disorder.[17] She also has taken anti-psychotic medications such as Depakote and Seroquel.[18]

In 1996, she filed a police report that her 28 year old boyfriend (she was 18 years old) had sexually "shared" her with 3 of his friends 3 years earlier. Police dropped the matter when Mangum failed to provide a written report of the alleged incident.

In 2000, she was arrested for driving under the influence of alcohol, but not convicted. Court records indicate that her driver's license was revoked but do not indicate why.[19]

In 2002, she stole a taxi from a man to whom she was giving a lap dance. A high speed chase then ensued, and when the deputy chasing her approached the stolen taxi on foot, she tried to run over him. She pleaded guilty to misdemeanor charges of larceny, speeding to elude arrest, assault on a government official and driving while impaired. She was sentenced to 3 weekends in detention.[20][21]
