One dead, two injured in Harlem collapse…

Firefighters in desperate rescue effort at Columbia University site.

Three demolition workers from company with ties to the mob were trapped in the rubble of a Harlem building when tons of reinforced concrete crashed down on them Thursday, killing one worker and
seriously injuring two others.

Juan Ruiz, a 69-year-old grandfather who was about to retire, died shortly after he and another construction worker were pulled out of the twisted debris.

As anxious co-workers looked on, firefighters were tearing through the wreckage in a valiant effort to reach the third trapped worker, 60-year-old King Range.

“Help me!” Range cried out as firefighters guided by his pleas found him inside a crevice of crumbled concrete, his left arm pinned by a half-ton slab.

“There was a void in there,” FDNY Captain Robert Morris of Rescue 1 in midtown said later. “He was basically saying, ‘Help me.’ ”

Forty-five minutes later, firefighters carried Range out of the ruins.

“He was really banged up, but he talked all the way to the ambulance,” said a firefighter who helped get him to St. Luke’s Hospital.
