A witness who watched the woman's heartless moment says she knew exactly what was going on behind her.
The tourist had been watching the drama unfold for up to 25 minutes before she pulled out her phone and took the shot.
Police eventually saved the man's life - talking him down from the bridge.
The woman, who had long blonde locks and was wearing a matching scarf and headband, held out her camera phone and appeared to make sure that she captured the bridge jumper in the background of her shot.
During that time, police boats roared through the water and a police helicopter buzzed overhead as officers inched out toward the desperate man.
‘As she took her picture, about 10 seconds later the jumper walked down. She was a tourist, I’m sure of that.’
When a reporter for the New York Post asked the woman for her name, she suddenly became camera shy and refused to talk.
