BRIGHTON, Colo. -- A former baby sitter is being ordered to serve ten years in prison for the shaking death of an infant girl nearly three years ago.

A district judge handed down the sentence Thursday to Ana Rosa Garay, 26.

Garay had been either in hospitals or jail since five-month-old Keyla Crystal Santos died in January 2004, and will receive credit for time already served.

Garay pleaded guilty earlier this year to criminally negligent child abuse resulting in death, admitting she violently shook Keyla after the infant started crying.

The infant died after she was removed from life support.

Defense attorney David Givens called Garay a poor illegal immigrant who'd suffered severe depression while growing up in Mexico.

She could have received a sentence of as long as 16 years.
