A state agency is investigating after a 15-year-old boy who went missing from his Elmont school last week was fatally struck by a car on the Southern State Parkway, officials said.

Christopher Williams left Martin de Porres School for Exceptional Children during school hours on Sept. 4. He was reported missing by the school around 1:30 p.m. — about 15 minutes after he was hit by a car in North Valley Stream, Newsday previously reported.

A spokeswoman said the center "cannot comment on pending investigations."
