Investigators Review Underwater Images In Search For Sierra LaMar

SAN JOSE (KCBS) – The Santa Clara County Sheriff's department is reviewing sonar images taken from local reservoirs as the search continues for a missing Morgan Hill teen.

15-year-old Sierra LaMar of Morgan Hill has not been seen since the morning of March 16th.

Earlier this week, sheriff's officials took sonar images of Chesbro and Uvas reservoirs. The department plans to send out dive teams later this week to investigate any suspicious objects.

KCBS' Matt Bigler Reports:

Meanwhile, volunteers gathered for another day of searching Wednesday at Burnett Elementary School. According to search director Brian Miller, volunteers are looking in areas previously unsearched.

"Today we're going to be heading south of Gilroy, and covering some areas that have been recommended down there," said Miller.

Sierra LaMar has been missing for more than three weeks, but her mother Marlene said she is trying to stay optimistic that she will see her daughter again.

"I'm not going to give up," said Marlene LaMar. "I am determined, and the determination is what's giving me the energy to continue. The public is as well. People are coming back for a third and fourth time. I'm truly astounded."

So far, about 3,500 people have helped in the search for Sierra since she disappeared.
