It’s all the little things, even those minor annoyances, that Sierra LaMar’s mother says she misses as search for her daughter continued into its sixth week.

Standing inside the search center at Burnett Elementary School Wednesday, Marlene LaMar fought off waves of emotions and tears to talk about the case, her family’s life without Sierra and the search for the missing teen with reporters.

“As time goes on and those familiar sounds that you are used to hearing all the time and I never thought I’d be saying this but we miss the rap music,” she said. “We really miss her. “

Meanwhile, sheriff’s deputies continued to scour nearby waters for any sign of the teen. On Wednesday, divers were in the waters of the Calero and Anderson Reservoirs .

Sources have also told KTVU that DNA found on one of the items linked to Sierra that have been recovered by investigators.

“We talk with them pretty consistently,” she said of the family’s contact with investigators. “There is always law enforcement at the search center.”

As the hours have turned into days and then weeks, the stress has taken its toll on Sierra’s family.

“Emotionally, it’s unbelievable that something like this could happen,” Marlene LaMar told reporters. “You are not prepared for a situation like this. It’s an unfortunate reality. We all like to believe our child is going to be safe and we are doing everything to keep them safe as a parent.” When asked if Sierra there’s was a message she wanted to send her daughter, Marlene LaMar responded: “Sierra just be strong. We are out there looking for you. We are very hopeful you will be strong enough to pull through this and come back to us… We all love you dearly.” Marlene LaMar – wearing a pink bracelet that reads – “Sierra is everyone’s daughter” -- has also returned to work, but find it difficult not to think about her missing daughter.

“I’m back to work and hard to focus,” she told reporters. “It’s harder to rest.”

Sierra, 15, has been missing since March 16, when she did not show up for school. Hundreds of volunteers have searched fields and open spaces for any sign of the missing teen since then.
