Minnesota babysitter admits to unintentionally killing 5-month-old

Tyanna Jabree Graham stood in a Ramsey County courtroom this week and admitted to unintentionally killing a 5-month-old boy while she was babysitting the infant last winter. The 19-year-old St. Paul woman pleaded guilty Monday to one count of second-degree murder in the death of Jamir P. Dunagan.
