The family of missing teenager Sierra LaMar held a rally in Fremont Friday night -- one day after the man suspected of slaying the girl made his second appearance in court.

About 150 people showed up at at the flagpole at Washington High School, where the 15-year-old attended during her freshman year.

Several people lit candles, wore wrist bands with Sierra's name and displayed signs and pictures of the missing girl. But most of all they wanted everyone to know they haven't given up the hope that she is still alive.

Sierra's father, Steve LaMar, told KTVU he met with sheriff's investigators Friday, who interviewed him again about his daughter.

"(They asked about) Sierra's activity and social media, texting, that kind of thing," LaMar said.

Steve LaMar said it was too painful for him to attend Thursday's hearing where 21-year-old Antolin Garcia-Torres, the man suspected of abducting and killing Sierra LaMar, appeared in court. Steve LaMar said he's seen Garcia-Torres on television, and he said many things come to mind.

"Anger, questions, 'Why?' All those kinds of things," LaMar said.

No body or murder weapon has been found.

"We don't have any indication that she's not alive, so as long as I have that I'm continuing," Steve LaMar said.

There's been an effort to uplift the spirits of those who love the missing teenager. Family friend Joanna Isom was originally thinking of planning a vigil Friday, but after speaking with Sierra LaMar's mother, she decided to hold a rally.

"People were giving their condolences and their rest-in-peace-Sierra's, and I was like, 'Stop it, we're not even there,'" Isom said. "But together, we want to convey to the public and the children there's still hope."

Isom's daughter Tatianna has been spreading the word around campus about the event, which is being dubbed the Faith and Hope rally.

"We want to make this one happy to remember her and remember what kind of person she was and how bubbly she is," said Sierra LaMar's friend, Tatianna Isom. "We want to keep her alive."

A search is planned for their daughter Saturday, starting at 8 a.m. in Morgan Hill.

"We're not giving up,” said Sierra’s sister Danielle LaMar. “We still need the support. We haven't found Sierra yet, so we're just trying to encourage people to keep coming out and not give up.”
