Sierra LaMar's family and friends refuse to believe she's dead.
"We really feel she's out there despite what the Sheriff's office has said," Joanna Isom, a LaMar family friend said. "There are certain reasons why they have to say what they say. But we believe she's out there and we're not stopping until she comes home."
The 15-year-old Morgan Hill teen vanished on March 16. Antolin Garcia Torres was arrested last week and charged this week with LaMar's murder and kidnapping.
Hundreds attended a candlelight vigil and rally at Washington High School in Fremont on Friday night.
LaMar went to Washington High before moving to Morgan Hill with her mother last year.
The LaMar family has made it a goal to attend as many of these rallies as they can.
They say it's important to boost the spirits for everyone involved.
"Keep a presence around people who are helping us," said Steve Lamar, Sierra's father. "That motivates them and helps them. Helps inspire them if we stay upbeat and visible."
Another search for Sierra LaMar will start at 8 a.m. Saturday morning at the Sierra LaMar Search Center in Morgan Hill.
