South Bay search crews took to the water Friday in the hopes of finding clues to the disappearance of Morgan Hill teen Sierra LaMar, but came up empty once again.

Search efforts continued in the midst of emotional turmoil for family and volunteers in a week that started with the arrest of a suspect and was capped by Thursday's discovery of the body in the East Bay.

Pleasanton police issued more information Friday about the human remains found in a trash can on a roadside late Thursday morning, announcing that the body belonged to a woman and determining some details about her clothing and appearance.

Investigators contacted the Santa Clara County Sheriff's office on Friday, but said they do not believe it is the body of missing Morgan Hill teen Sierra LaMar.

Meanwhile, the Santa Clara County Sheriff's dive team wrapped up a week-long search at Uvas Reservoir near Morgan Hill at around 5 p.m. Friday.

The team has been searching for 15-year old Sierra LaMar since she disappeared March 16th.

On Monday, 21-year-old Antolin Garcia-Torres was arrested and charged with her kidnapping and murder. On Thursday, he made his first court appearance.

Sierra's father Steve LaMar said it is painful knowing search teams are looking for a body.

"That's what they need to do, but for us the family, we're keeping hope that we're going to find Sierra still alive," said LaMar. "So if we have that sliver of hope, we're gonna stick with it and keep going."

The sheriff's department maintained it has not focused on Uvas Reservoir just because the suspect's mother said her son told her he was at Uvas around the time of sierra's disappearance.

In any case, the search came up empty.

"To date, they have not located anything of evidence pertaining to the Sierra LaMar case," said Santa Clara County Sheriff's Dept. Sgt. Jose Cardoza.

Though the LaMar family officially shut down the center for the holiday weekend, on Friday a select group of experienced searchers met inside to plan a Saturday search. Sources asked KTVU not to disclose locations.

Steve LaMar thanked the volunteers.

"We're so grateful for that, and so thankful that people have that much care and support for us," said LaMar.

That support will continue. A Sierra LaMar fundraiser got underway Friday afternoon at the Jason Stephens Winery on Watsonville Road in Gilroy.

A rally of hope is planned next Friday in Fremont.
