A New York woman who fatally injured her 5-year-old cousin and hid him in a snowbank while he was still alive has been sentenced to 18 years to life in prison.

Tiffany VanAlstyne was sentenced Thursday morning in Albany County Court.

The 20-year-old VanAlstyne admitted beating and choking Kenneth White while caring for him in December 2014 at her home in the town of Knox. She pleaded guilty in November to depraved indifference murder of a child.

VanAlstyne initially told police men kidnapped the boy, prompting authorities to issue a statewide Amber Alert. She later admitted she covered his body with snow after tossing him into a culvert near the home, then called 911 and claimed the boy had been abducted.

Police later found the boy's body.
