3.5 Million Watch Viral Video of Woman Falling Into Mall Fountain

Cathy Cruz Marrero threatens to sue those who released the clip.

A woman is threatening sue after she was caught on camera falling into a fountain at a shopping mall -- and the video was viewed by more than 3.5 million people on YouTube and morning TV shows.

"I was dumbfounded," Cathy Cruz Marrero said on Good Morning America Thursday of the tumble, which she took while texting a friend from church. "I admit it was funny, but nobody took my feelings into consideration. Nobody called, 'Are you OK?'"

Her lawyer says they "intend to hold all parties responsible," even if that includes legal action. He thinks a security guard captured the footage on a cell phone camera, and then posted it online.

You can hear people laughing as Marrero trips into the water.
