Divers were out for the last formal water search Monday in the hunt for Sierra LaMar, a 15-year-old Morgan Hill girl who was last seen March 16 and whose body has not yet been found.
Santa Clara County Sheriff's Sgt. Jose Cardoza said that the last formal search will occur in the waters of the Uvas Reservoir. Any future water searches will be based on tips and leads, Cardoza said.
Antolin Garcia-Torres, 21, of Morgan Hill was arrested and charged last month for the murder and kidnap of Sierra. He is in jail without bail.
Authorities say that DNA on Sierra's belongings found near where she was abducted is a similar match to Garcia-Torres'. His family has previously told NBC Bay Area that they don't believe Garcia-Torres would have, or could have, killed Sierra.
Experts acknowledge that prosecuting a homicide without a body is difficult.
