VIDEO: A 14-year-old boy has died after rescue crews pulled him from the water unconscious and performed life-saving measures on Monday, fire officials said.
Around 2 p.m., first responders received a report about a missing teen boy near Crissy Field.
San Francisco Fire Department said the boy was reported to be struggling in the water.
Authorities said the boy was at the beach with a group of friends who tried to rescue him when they saw he went under water. They called 911 when they could not find him.
Cristine Balderston was on the beach when it happened. She jumped in to help.
"I was in the water swimming around trying to find him for about five or 10 minutes before the rescue team got there," Balderston said. "I just wanted to help any way I could and I wish I would have been able to."
The boy reportedly did not know how to swim.
After about 90 minutes underwater, a rescue diver found the young man and brought him to shore. Paramedics tried to bring him back to life.
