Just days before he was going to start high school, a Hudson Valley teen drowned.

On Monday around 9 p.m., the Putnam County Sheriff's Office responded to a 911 call for a drowning at Tonnetta Lake Beach in the Town of Southeast.

First responders noticed a group of people at the end of the dock and an adult man in the water.

The adult told police he was nearby when he heard cries for help. He dove into the water to attempt to find a teen but wasn't able to find him.

Witnesses told police, 14-year-old Oscar Gonzalez of Southeast was paddleboarding with three friends when the paddleboard they were on, turned over and Oscar disappeared under the water.

Just before 10 p.m., members of the Mahopac Falls Fire Department Dive Team recovered Gonzalez who was transported to a nearby hospital where he was pronounced dead.

Gonzalez was about to start classes at Brewster High School, police say.
