Reason behind model's tragic suicide still unknown...
Ruslana Korshunova, just 20 years old, appears to have jumped to her death in Manhattan's financial district. The sad news has shocked her friends and family, who saw Korshunova as a kind woman, climbing the ranks of the fashion industry after gracing covers of French Elle and Russian Vogue.
The pal said that Korshunova had just returned from a modeling gig in Paris and seemed to be "on top of the world."
"There were no signs," he said. "That's what's driving me crazy. I don't see one reason why she would do that."
