The FBI and NYPD have ended the search for Etan Patz, after new clues led them to a basement near where he lived in New York City. Patz, who disappeared in 1979 at the age of 6, was one of the first cases to have his picture printed on milk cartons. Investigators found one stain on the basement wall that is being tested. "A stain on the wall is being tested [in a laboratory] but it's inconclusive what that's about,” a source told Reuters. “The digging has been done. There were no bones or obvious human remains found."
