By Louise Boyle UPDATED: 18:11 EST, 28 November 2012 A morbidly obese woman, dubbed the 'half ton killer' after being charged with her nephew's murder, showed off her dramatic weight loss today as she broke her silence on the ordeal. Mayra Rosales originally told police she had accidentally killed two-year-old Eliseo by rolling on top of him while babysitting four years ago. However her 1,100lb frame became her defense - as investigators proved she was so heavy she could not have committed the crime. Rosales, from Texas, said on Tuesday that she despised the nickname. She appeared to have lost a significant amount of weight in photos posted on her Facebook page. Comments from supporters suggested that the 31-year-old had her stomach stapled earlier this month.
