In August 2001, an altercation in a parking lot led to the tragic death of Mary Moon. However, the authorities soon found out that the killer was none other than Mary’s sister. Explore Discovery’s’Twisted Sisters: Breaking Point’ tells how Mary’s relationship with her sister changed over the years, eventually leading to murder. So if you’re wondering what happened in this case, we’ve got you covered.
How did Mary Moon die?
Mary Parr Moon was born in June 1970 to John and Charlene Parr. The 31-year-old was described as a loving and caring person. Mary was religious and was married to Jay Moon at the time of the incident; they married in October 1999. She was known for loving the outdoors and spending time gardening. Mary had attended beauty school in the past and was working as a hairdresser in a local saloon when she died.
On August 25, 2001, around 1:30 PM, a man named Erik Anderson called 911 after seeing two women fight in a parking lot in Kerrville, Texas. First responders found Mary with four stab wounds; one of them pierced her heart. She was immediately taken to hospital, but later succumbed to her injuries. By this time, authorities already had the attacker in custody.
Who Killed Mary Moon?
Police had arrested Mary’s older sister, Ana Weslene Hatton Roybal, then about 37 years old. Erik had stated that he was driving past the 720 Club in Kerrville with his wife when he saw Mary and Ana arguing. According to him, Ana threw away a knife and started running when he confronted her. Erik went after Ana and eventually caught up with her at the club, where he subdued her until the authorities arrived.
As part of the investigation, the police began to investigate Ana’s life and her relationship with Mary. According to the show, Ana struggled to keep a steady job during her 20s and her family disapproved of her choices. She had become pregnant and eventually gave birth to her son, Michael, in 1986. But immediately after, Ana left for California, leaving her grandparents to take care of her son. She soon lost custody of Michael.
After Ana and Mary’s mother died in 1995, Mary began to care for Michael. In the years that followed, problems and disagreements between the sisters ended in a fatal way. It was mentioned on the show that Mary sold their mother’s car that was promised to Ana and never gave her the money. Ana then accused Mary of stealing her Social Security checks and having sex with her ex-boyfriend, and having men molested them.
Authorities found out that Ana had previously met Mary at the local church and stole a knife there. Some time later, Ana asked her sister to drop her off at the 720 Club. During the drive there, the sisters started arguing and the anger boiled over into a fierce fight in the parking lot, in which Ana stabbed Mary. She was charged with murder in September 2001.
Where is Ana Weslene Hatton Roybal now?
Ana pleaded not guilty at her trial to insanity. The defense provided evidence pointing to her history of bizarre behavior. According to the show, Ana had been on medication for schizophrenia and other mental illnesses. Experts further testified that she was delusional when the attack took place. However, the jury found Ana guilty of murder and in August 2002 she was sentenced to 60 years in prison. Records show that Ana is trapped in the Skyview Unit in Rusk, Texas. She will be eligible for parole in 2031.
