DENVER – Denver police are searching a neighborhood for a 7-year-old boy missing since Monday afternoon.

Police, who are getting help from the FBI and other law enforcement agencies, stopped drivers and looked in car trunks and campers Tuesday for 7-year-old Jordan Vong.

Police spokeswoman Marika Putnum says police are considering “every angle” in the search for him. She urged residents to look in their backyards and check sheds and other places where a 3-foot-7 boy might be able to hide.

He was last seen at about 4:30 p.m. Monday.

An Amber Alert hasn’t been issued for the boy because police say not all the criteria for an alert has been met.
