Emergency personnel were called around 8:15 p.m. about a car near a boat ramp in Boundary Line Lake off of McArthur Road.
Balloons and a small cross now mark the spot where 17-year-old Brenton Briggs died on New Year's Day.
"I'll miss him. It's going to be boring without him there," said Brigg's classmate, Gabriel Evans. "It's real hard right now on us. He was a really good member of Reid Ross. He was friends with everybody."
Investigators say Briggs and at least three other people were at the lake on New Year's Day. About 8:20 p.m., Fort Bragg Fire and Emergency Services responded to reports of a vehicle in the water near the boat ramp.
Eyewitnesses told investigators Briggs had climbed in the vehicle as it began to slide backwards into the water and submerge. Briggs was unable to get out. None of the others who were out at the lake Sunday night was injured.
Briggs was a student at Reid Ross Classical School, which is a year round school that was still on break. School gets back in session next week and the principal says he plans to have extra counselors on hand to help students deal with the emotional loss.
Briggs' death is under investigation by special agents from the U.S. Army Criminal Investigation Command.
