Rachel Aliza Nisanov, 13, and her sister Aviva, 16, were the two teens who crashed into a dock on a personal watercraft in the Intracoastal Waterway in Fort Lauderdale on Tuesday, killing Rachel.

Rachel Nisanov's brother Yonah said their father jumped into the water to save her and her sister, even though he couldn't swim.

Rachel Aliza Nisanov, 14, was killed after the watercraft her sister was driving crashed against the docks during a graduation trip in Florida — with her heartbroken father, Rabbi Shlomo Nisanov, jumping into the water to desperately try to save them both.
