The other victims were Carla Vallejos Blanco, 29; Daniel Thompson, 34; Tristan Hill, 29; and Brian McDaniel, 26.
Emergency workers reached the helicopter, but the passengers were tightly harnessed in the open-door helicopter and had to be cut out, Fire Department of New York Commissioner Daniel Nigro said. The helicopter pilot, the only survivor, was able to free himself.
"(Cadigan) was always happy and full of life," says friend and former girlfriend Jordan McDaniel. "He was the type of guy that would do anything for you. And (he) was extremely ambitious with a bright future."
Business Insider, at which Cadigan interned, agreed.
"He was a smart, talented, and ambitious young journalist and producer who was well-liked and made a big contribution," the company said in a statement. "Our hearts go out to his family and friends."
