WACO -- Two more victims drowned in lake waco this weekend.
33-year-old Juan Castillos and 15-year-old Nicholas Carter were swimming at Airport Beach Park.
When Carter lost his footing and went under. Castillos went in after Carter to save him but never came back up.
"Two bystanders came over to help and was only able to pull the 33-year-old male out of the water, and they did CPR on him and they weren't successful," said Sgt. Lanier.
The tragedy happened just two weeks after 18-year-old Atahualpa Rosas died swimming at the same beach.
Neither Carter nor Rosas knew how to swim.
