A 39-year-old woman is in jail after authorities accused her of being responsible for the head injury that killed her 3-year-old adopted son.
The El Paso County Sheriff's Office says Michelle Dosdall, of Peyton, Colo., faces first-degree murder and child abuse charges for the death of the boy, who was taken off life support Wednesday after being declared brain dead. Sheriff's officials say Dosdall surrendered to authorities Friday and is being held without bail.
Dosdall told a detective that the boy, Tristan, was neglected in foster care before she adopted him and that he needed to do exercises as part of his physical therapy. Dosdall says sometimes the boy would go limp and fall backward, hitting his head on the carpet, when he didn't want to do the exercises.
