The sheriff's office says Tuesday's dive missions are not related to new leads in the case, but there is relevant new information coming from the crime lab. Preliminary test results are back on evidence in the case.
"Although they're not specifying which evidence items led to these new leads, they are saying that they are positive, they are fruitful and that it has led to some additional leads for them to follow up on," Sgt. Jose Cardoza with the Santa Clara County Sheriff's Office said.
