A Wisconsin woman facing charges in her 12-year-old son’s death late last year claims that his rapid weight loss — he weighed just 56 pounds when he died — was because he had a terminal illness. Prosecutors, however, say Tina Beauprey simply didn’t feed or care for the boy, WLUK reports. A probable cause statement noted an autopsy report that determined the boy died from starvation, classifying his death as a homicide. According to the Muscular Dystrophy Association, the disorder mostly strikes boys, who typically live into their 30s or even 40s. The disease presents as progressive muscular weakness and does not typically include rapid weight loss.
