Classes are back under way at a northeast Ohio high school where three students were shot and killed last winter.
Students and teachers at Chardon High School said they are hoping for a normal school year.
The school's principal says it will be a challenge to get back into a routine. The school has added a new resource officer and classroom door locks.
The Associated Press reports that parents spent weeks archiving cards and notes that came into the school after the shooting.
A teenager charged with killing three students in the school's cafeteria is undergoing psychological evaluations and has been charged with aggravated murder and attempted aggravated murder.
