Police said Trent was driving his 1997 Mazda pickup north on Horton just north of the Middle Road traffic circle in Riverhead when the boy stepped into the road at about 8 p.m.

Trent was unable to stop the truck in time, police said, striking the boy. It was not immediately clear if the boy was accompanied by an adult.
