An Ankeny man is scheduled to be sentenced this week for killing his infant daughter.
A Polk County judge convicted 22-year-old Ryan Trowbridge of first degree murder in October.
In July 2010, 4-month old Rylee Trowbridge was found unresponsive at the family’s home.
Trowbridge originally told police his daughter was injured when she slid between a mattress and headboard while taking a nap.
An autopsy found the baby’s injuries didn’t match his account.
His sentencing is scheduled for Tuesday.
Trowbridge is expected to be given a mandatory sentence of life without parole.
