An Ankeny man has been sentenced to life in prison for killing his infant daughter in 2010.
Ryan Trowbridge was sentenced Tuesday in Polk County. He was convicted in October after a bench trial of first-degree murder and child endangerment causing death.
Prosecutors say injuries on 4-month-old daughter Rylee were consistent with being grabbed and shaken. Trowbridge told authorities he put his daughter on a bed for a nap and then discovered her trapped between the headboard and mattress.
Trowbridge's attorney says his client will appeal his conviction.
