An SUV driver hit them -- witnesses reported it appeared intentional -- and sped off. Later Wednesday, well after news of the charges, the police chief of neighboring Westfield shared on social media that he was related to the suspect. He didn't specify the nature of the relation, but said the teen is not his son nor a "member of his immediate family." The police chief also said he lives in the same neighborhood as one of the victims, whom he identified as Isabella Salas. Prosecutors did not share where the suspect was being held or when he was expected to make his first court appearance.
