NEWBURGH, N.Y. — Dozens of officers from several police agencies continue to scour the city of Newburgh looking for a 4-year-old boy who went missing Monday.

Police say Marc Anthony Bookal vanished from his family’s apartment Monday. They’ve been using dogs and dive teams have been checking the nearby Hudson River but on Thursday reported no new information in the case.

Cory Byrd, the boyfriend of Marc’s mother, has been charged with endangering the welfare of a child. Police say the boy was in Byrd’s care when he vanished. The 30-year-old Byrd also was charged with a parole violation. He’s being held in Orange County Jail.

Police haven’t called Byrd a suspect in the boy’s disappearance.
