Sierra's mother told ABC7 News that she has recently been contacted by a San Jose Sharks player to see if he can encourage Sharks fans to participate in Saturday searches. The organizers at the search center are trying to keep hope alive.
Authorities charged Antolin Garcia-Torres with the kidnapping and murder of Sierra, even though her body has not been found.
Garcia-Torres was quickly identified as the suspect. Detectives interviewed him twice three weeks after Sierra disappeared in March of 2012.
Sierra's father spoke to ABC7 News about the grand jury transcripts that were released. He says it's tough to hear about the graphic evidence. "It's upsetting and not the kind of thing I want to read about what possibly happened to my daughter," Steve LaMar said.
The 1,900-page transcript lays out a case against Garcia-Torres based on several pieces of DNA and forensic evidence. Her clothes had fabric fibers from his red Volkswagen Jetta. When detectives searched his car, they also found her DNA on an armrest and her some of her hair was found on a rope inside the trunk. His DNA was also found on a pair of her pants recovered in a field near her Morgan Hill home.
Legal analyst Steven Clark says Garcia-Torres implicated himself when first questioned by police. "He started to volunteer answers to questions that weren't asked. And the most damaging of which is regarding how his bodily fluids could be contained at the Sierra Lamar crime scene."
On Saturday, a team of searchers scoured some rough terrain near Morgan Hill. The searches continue much like they have since Sierra went missing in March 2012 and rewards are still available.
"There may be some people that have not ever come forward that would call our tipline," search coordinator Roger Nelson said.
Sierra's father says the family appreciates their dedication. "The more that we can find, the more it will help the case," he said.
Volunteers and family friends say finding her will also help the family get some closure.
