The Winnetka police and fire departments responded to Elder Beach around 1:25 p.m., Fox Chicago reported. 

When they arrived, they learned that Laidley was part of a boating group on the lakefront and had jumped into the water to help some kids who were tubing. 

While in the water, he began to struggle to swim and eventually drowned. He was pulled back onto the boat and given CPR.

The boat went back to the shore and paramedics tried to save him. He was taken to Northshore Evanston Hospital where he was pronounced dead, police said.

Winnetka is one of the Chicago area's wealthiest suburbs and one of the most affluent in the United States where the median household income was $250,000 or higher, according to U.S. Census figures. The city is also where the exterior shots for the house used in the Christmas classic "Home Alone" was filmed.
