He was described by his family as “the most special person ever.”

“He really created a life for himself. He literally took every opportunity he could find,” his sister-in-law, Lisa Guttman, said through tears.

Two people were hospitalized – neither with life-threatening injuries.

Dawn Kojima, 45, was taken to NewYork-Presbyterian/Lower Manhattan Hospital after the accident.

She was on her way to work on Worth Street Friday morning just getting a cup of coffee when the crane suddenly came crashing down, CBS2’s Brian Conybeare reported. She needed nine staples in her head to close a gash, and she was also left with a severely bruised leg, but she was expected to recover.

Meanwhile, Thomas O’Brien, 73, was taken to Bellevue Hospital Center with a head laceration. O’Brien, of Easton, Massachusetts, was in New York visiting his daughter who lives in the city.

O’Brien and Kojima’s conditions were described as “stable,” police said.

The FDNY said the third person — a firefighter — suffered a minor injury during the rescue and is expected to recover.

“This is a very, very sad incident. We’ve lost a life,” de Blasio said. “It was something of a miracle that there wasn’t more impact and thank God that the impact on people wasn’t worse.”
