The walls had no trace of blood, according to field tests conducted at the site, law enforcement sources told The Post. And it appeared that no human bones were in the cement, sources said.
Strands of hair were discovered but they don’t appear to match the blond locks of six-year Etan, who left his building at 113 Prince St. the morning of May 25, 1979, and hasn’t been seen since. Investigators are also not sure if the hair was human, sources said.
Investigators haven’t totally given up hope in finding clues in the basement and have sent blocks of cement to an FBI lab in Quantico, Va., for further analysis.
In 1979, the basement was the domain of Othniel Miller, a now-75-year-old handyman who did odd jobs around the Patz neighborhood. Cops interviewed Miller during the initial search for Etan after noticing freshly poured concrete on the basement floor, but they never dug it up.
