LAYTON — A man accused of shaking his girlfriend's 11-month-old daughter and throwing her onto a bed has been arrested.

Geary was watching the infant while his girlfriend, 20, was at work. Investigators believe he became frustrated with the child's crying and shook her. Police were called to hospital about 6:30 a.m. Tuesday by hospital staff.

The girl was brought to the emergency room at Davis Hospital & Medical Center unresponsive and in critical condition, according to police. The child was transferred to Primary Children's Medical Center and was listed in critical condition.
