Nicole Hughes says she had just split a brownie with her 3-year-old son Levi and was beginning to clean up after dinner when Levi snuck away. He slipped down to a pool at the family's vacation home. When Hughes looked outside, she just happened to glance over the balcony and saw him. She had not even finished her bite of the brownie when she jumped in the water after him. That's how fast it all happened. Levi did not survive.
