Police did not say whether the boy was related to Charles; other family members were in the car as passengers, a State Police spokesman said.

Leandra's Law was passed in 2009 after the death of Leandra Rosado, 11, who was killed in a DWI accident after the minivan in which she was a passenger crashed on the West Side Highway in Manhattan.
