MORGAN HILL - Even with all the help and man hours spent searching for missing teen Sierra LaMar, deputies and volunteers are no closer to finding her Wednesday night.
"Even though at first glace it looks fairly open and flat, there are a lot of places to look," said Jeff Thomas, director volunteer for Search and Rescue in Santa Clara county.
Up against time and terrain, Search and Rescue volunteers are trying to figure out the best places to search for LaMar.
Thomas is one of the volunteers leading the search.
He said what makes this search so difficult is Morgan Hill is a relatively rural, agricultural area with large fields, streams, ponds, ditches and tree lines.
After searching almost non-stop for LaMar since she disappeared 12 days ago, the possibilities of where she can be seem endless.
"When we go out and look now we're looking over hundreds of miles of an area so we have to figure out where to go look some places are better to look than others," Thomas said.
Volunteers combed a 12-mile radius of the teen's home after her cell phone and purse with clothes in it were found last week.
Still nothing.
"There aren't too many areas we're looking at to continue and we haven't turned up anything new or significant, so what we'll be doing is going over that data again, looking for things we may have missed," Thomas said.
That's where the hundreds of volunteers help, willing to do whatever it takes to find the missing 15-year-old.
"It keeps changing every day so who knows, hopefully we'll find something today," said Jennifer Fernandes, volunteer.
Volunteer searchers will be back in Morgan Hill on Thursday.
"You search until you're not finding any more clues until you run out of likely places to look," Thomas said.
