The 1993 disappearance of a 10-year-old Prince George’s County boy led to a nationwide FBI probe of Internet predators and the discovery of a pedophile ring. But the boy remains missing and the case of George Stanley Burdynski remains unsolved.

Burdynski, who was known as “Junior,” was last seen on May 24, 1993, pedaling his red bicycle near his parents’ house along the 4300 block of 40th Place in Brentwood.
