A second official says Pedro Hernandez was picked up late Wednesday in Camden, N.J., and is now being questioned by the Manhattan District Attorney’s office, which is heading the probe by the FBI and police.

No body has been recovered. Hernandez worked at a neighborhood grocery when the boy disappeared, and later moved to New Jersey.

The officials spoke to The Associated Press on condition of anonymity because they weren’t authorized to discuss the ongoing probe into the boy’s disappearance in 1979.
