In turn, school officials have been open to answer a flood of concerns from parents, especially in the days after Llorente's arrest and Sandra's disappearance.
"When things like this happen, it's personal to all of us," Tracy Mayor Burt Ives told ABCNews.com.
Like any other American town, Tracy has seen its fair share of sadness from car accidents and soldiers killed in Iraq and Afghanistan. But the rash of outrageous crimes in the last few months is something different.
"Getting national attention is not something we're used to," Ives said, "nor do we want to get used to (it.)"
Tracy, a suburb of the San Francisco Bay area is home to about 80,000 people. About 70 percent of its workforce commutes to the Silicon Valley, Ives said, yet the town still relies heavily on its agricultural roots growing tomatoes, alfalfa and peaches, among other crops.
The town was only 15,000 people strong in the 1970s, but has increased in popularity and population as the Bay Area continues to sprawl outwards. Ives said the residents are a mix of white and blue collar workers.
While Sandra's disappearance from a mobile home park -- some have called it a trailer park -- has painted the town as rural or backwoods, Ives said there are only a few such parks in town and Orchard Estates where Sandra lived is a "clean, nice little neighborhood."
"This could have happened anywhere," he said.
But it didn't -- it happened in Tracy.
Ives said that while the community is rallying behind Sandra's family – he called her the town's "little adopted daughter" -- they aren't too sure how to deal with her alleged killer's family.
"I think it's really hard to know how to treat them right now," he said.
"There's evil in this world and unfortunately, we got our slice of it as well," Ives said. "We'll bend, but we won't break."
