Greenwich parents who lost their 6-year-old son in a drowning are teaching children the importance of water safety through camps they founded.

A group of 100 kids ages 6-9 learned drowning prevention techniques and met with first responders at the Greenwich Boys & Girls Club this week.

The ZAC Foundation hosted the camps. Karen and Brian Cohn started the Zac Foundation in honor of their son Zachary. They say Zachary drowned in their pool after getting caught in a drain 16 years ago.

The first ZAC Camp was held at the Greenwich Boys & Girls Club in 2011. The camps are now offered for free at around 20 Boys & Girls Clubs across the country.
