Dive team to re-scan reservoir for Sierra LaMar


The new search, however, is not based on tips or leads. Instead, investigators are hoping the dive team's new side-scan sonar equipment might uncover new evidence.

15-year old Sierra disappeared three months ago on her way to school and has not been found. Antolin Garcia-Torres is charged with kidnapping and killing her based on DNA evidence found in his car and on her discarded clothing.
