What We Know About Nathaniel Berhow, the Saugus High School Shooting Suspect

Nathaniel Berhow was described as quiet student, avid hunter and cross-country runner.

The 16-year-old who authorities say opened fire Thursday at California's Saugus High School has died.

According to CBS News, Nathaniel Berhow died of a self-inflicted gunshot wound, after allegedly killing two other students and wounded three others.

Berhow had a girlfriend and was not a loner, but reports said he fell apart two years ago when his father died suddenly from a heart attack. His son grew up around guns and often accompanied his father on hunting trips.

The teen opened fire on Friday in a quad area at his school before classes started, authorities said. 

Two teens were emerging Friday as unsung heroes after they began raising money to purchase gunshot wound treatment kits for every room at the northern Los Angeles County high school.
