A Massachusetts man who tried to rescue two people fell into Lake Tahoe and was found dead Sunday afternoon, authorities said.

Boston resident Sayen Sengupta, 27, was operating a rental boat carrying 13 people near Dollar Point Pier around 5 p.m. Saturday, the Placer County Sheriff’s Office said.

Two passengers, who were being towed in inner tubes, fell into the water and became distressed, the sheriff’s office said. Sengupta dove after them, slipped underwater, and never resurfaced.
