It was eventually discovered that Mayra lied about the circumstances surrounding her nephew’s death in order to protect a real killer – her sister Jaimie Lee (the mother of the child). It turned out that Jaimie Lee killed her child by beating him with a hairbrush when he refused to eat and fled to Mexico, where she was eventually caught by the authorities.
Once she was cleared of all charges, Mayra had to figure out a way to provide for the surviving children of her sentenced sister. She knew she had to get healthier, otherwise she wouldn’t be able to support her new-found family.
With all of that media attention, Mayra had to make countless embarrassing confessions. Like how she had to buy a king-size bed to accommodate her enormous body. How she had troubles standing up from all that extra weight she was carrying. Or how she had to ask people to do even the easiest tasks for her. She clearly needed to do something drastic in order to help her own health.
