Basement may hold clues in NYC blast that killed 8

NEW YORK (AP) — Emergency workers are still removing debris from the site of a deadly explosion at two New York City apartment buildings that killed eight people.

Construction machinery was offloading debris from the site Saturday morning. Workers were expected to reach the basement level, clearing the way for investigators to search for clues that might reveal what caused the blast.

A few blocks away, underneath the Metro-North railroad tracks, several wrecked vehicles were still covered in bricks and debris.

Officials say truckloads of scattered material will be sifted for any traces of human remains that might not have been found at the site.

The rescue operation was continuing in case unknown people were buried beneath the rubble.
