Roland Q. Lyles, 31, of Orange, was initially arrested and charged on June 27 with aggravated assault following a collision, Middlesex County Prosecutor Yolanda Ciccone and Edison Police Chief Thomas Bryan said in a joint statement.
Additional charges were lodged against Lyles on Wednesday after the 51-year-old crash victim died on Tuesday, June 30, they said. The deceased motorcyclist was identified as Richard Diaz of Brooklyn.
