(CBS) Just seeing a lifeguard instills a sense of security.

But having a lifeguard at water’s edge — doesn’t always mean your pool is safe.

“Early Show” Consumer Correspondent Susan Koeppen told the story of Yoni Gottesman.

Yoni was just 4 years old when his parents took him to summer camp.

His mother, Anat Gottesman, said, “I remember when I left him in the morning. He said, ‘Mommy, I’m so happy. Bye bye. We’ll see you later.'”

But that was the last they would see Yoni alive.
