In 2008, Mayra Rosales was nearly 1,000 pounds and on trial for the murder of her 2-year-old nephew after she claimed that she fell on the toddler and crushed him. The controversial trial made headlines and brought Mayra the nickname “Half-Ton Killer.” These days, the 33-year-old Texas woman has been cleared of all charges and has lost over 800 pounds, which TLC highlighted in their new special, “Half-Ton Killer: Transformed,” that aired last night (December 4). So what happened?

First, Mayra’s sister, Julie (the boy’s mother), was found guilty of the child abuse that ultimately killed her son. She is now serving 15 years in prison. Mayra admits that she covered for her sister at first, as she felt she was going to die anyway: "I was already giving up in life, and the way I saw it, when they began saying I was going to get capital murder charges, I really saw it like they were doing me a favor."

After she realized what her sister had done, she helped the prosecutors make their case. After that, all charges against Mayra were dropped. She’s since turned her life around, working with an obesity specialist to lose the 600 pounds necessary before undergoing gastric bypass surgery. Throughout, Mayra stuck to a strict, high-protein diet.

At the time of the TLC special, Mayra was down to 350 pounds. She is also living in her own apartment and is currently employed at a hospital, helping to counsel patients with obesity issues.

Mayra says that her sister’s surviving children were her inspiration to get healthy, and she’s currently fighting to gain custody of them.

"They were first to know when I was able to stand up for the first time, and then when they saw me walking, they saw me walk in the door, they were very excited ... They are my motivation," she tells ABC News.
