NEW YORK (AP) -- New York City's fire commissioner says rescue workers have searched the rear basement of the site of a deadly gas explosion, but haven't yet reached the area where the piping and meters will help explain what caused the blast that killed eight people.
Fire Commissioner Salvatore Cassano said Saturday that the investigation of the piping and the meters will likely start on Sunday when workers can reach deeper into the basement.
Cassano says he believes the National Transportation Safety Board can start pressure-testing the pipes on Sunday.
Cassano says no more bodies have been found in the rubble. He says about 15 percent of the debris is left on the site.
