The parents of a 5-year-old Brooklyn boy found near a busy intersection are speaking out after learning he wandered from his school building. The boy, Amani, walked out of the Community Partnership Charter School in Clinton Hill this past Tuesday. He ended up several blocks away, where a crossing guard spotted him and called 911. "This could have took a turn for the worse," said father Byron Smith. "This is a parent's nightmare." School Superintendent Denniston Reid says the incident was isolated and that he will work to make sure it never happens again. City Councilwoman Letitia James (D-35th District) says her office will fund the school's increased security costs.
