The Santa Clara Sheriff's dive unit Wednesday morning finished searching another percolation pond near Ogier and Monterey roads in Morgan Hill for Sierra Lamar, the teenager who disappeared near her home a month ago.
Wednesday searchers received permission to look in three private ponds.
Then if all goes according to schedule, they'll wrap up at Calero Reservoir. For the first time, the dive unit is using side scan sonar, which can peer through murky silty waters and provide high resolution video images of what lies underneath.
To the lay person, the images are a bunch of yellow squiggly lines. But the trained eye can detect anything from cars to weapons and even bodies.
If they do see something possibly related to the Sierra Lamar case, a diver will go underwater and check it out. Not far from the pond, Sierra's mom Marlene prayed with volunteers before they headed out to search for her daughter.
In spite of the nice weather, the turnout wasn't as high as it has been in the past. But Marlene Lamar is grateful nonetheless knowing that people in this community still care about her child.
In the month since her 15-year-old daughter disappeared, it has been the hardest when the house is quiet.
"I never thought that I'd be saying this, but we miss the rap music, you know," she said. "We really miss her."
The KlaasKids Foundation will be registering volunteer searchers at Burnett Elementary until 1 p.m. Wednesday afternoon.
The Foundation will launch two more searches Saturday and Sunday.
