A 6-month-old boy was seriously hurt after he was ejected from his mother’s car during a crash and tossed 25 feet into the snow. The Cumberland County Sheriff’s Office said the boy’s mother, Chynna Blaney, 19, drove through a stop sign in Raymond just before 5 p.m. Thursday and was struck by a pickup truck. The boy was thrown from his safety seat in the back of the car. Blaney and her son were hospitalized with serious injuries. The driver of the truck — Angie Horler, 35, of New Gloucester — required treatment for minor injuries, while her two children, ages 2 and 5, were unhurt.
