A man has been sentenced to 12 to 15 years in prison for allowing a brutal beating that left his stepdaughter with a severe brain injury and put her at the center of a right-to-die case in Massachusetts.

Jason Strickland was convicted in November of five of the six charges related to the 2005 beating of 11-year-old Haleigh Poutre.

The jury didn't believe Strickland was present for the beating, but said he would have known that leaving the girl with his late wife, Holli, could pose a serious risk.

The abuse left Haleigh in a coma. After she spent months on life support, child welfare officials got permission to remove her feeding tube. But soon after, Haleigh began to show improvement.

Now 14, the girl lives in a Boston rehabilitation facility.
