Florida babysitter charged with murder 37 years after baby shaken

36 years ago, babysitter Terry McKirchy was sentenced to weekends in jail for three months for shaking a 5-month-old boy so severely that he suffered permanent brain damage. But she now faces a possible life sentence for murder after a medical examiner said the victim succumbed to those injuries at the age of 35, after a life with severe mental and physical disabilities.
