A Windham woman and her toddler escaped serious injury when her car crashed into a building early Friday morning in Casco.

Police say 22-year-old Kathryn Worster crashed her 2008 Ford Escape into a building at the intersection of Route 302 and Quaker Ridge Road at 6 a.m. Friday.

Worster’s vehicle was totaled and the building sustained significant structural damage, according to Capt. Scott Stewart of the Cumberland County Sheriff’s Office.

Worster was wearing a seat belt and her 2-year-old daughter was restrained in a 5-point child safety seat. Neither sustained any serious injuries, Stewart said.

Police believe speed and fatigue are the main factors that led the crash and say alcohol was not involved.
