The State Patrol will be flying a search pattern over the general McCleary area, scanning the ground for Lindsey Baum with a heat-sensing camera. The video will be fed live back to the ground where officials can see the results in real-time.

Cadets from the Civil Air Patrol are also joining the growing search party for the girl, who disappeared while walking home on Friday. And police scoured surveillance videos from the town's businesses looking for any clues.

Meanwhile, Baum's mother issued a desperate plea that if someone took her daughter, to let her go.

"If somebody does have her, just let her go. Drop her off at a restaurant or gas station where she can get to a phone and call," Melissa Baum said.

The mother believes her daughter would never have willingly gotten into a stranger's car.

"If somebody grabbed her she would have put up a fight," she said. "She would definitely scream."

The missing girl was going to walk the ten blocks to her home on Mommsen Road from a friend's house, which is roughly a 10-minute walk. But something happened in that short distance, and she never arrived home.

On Tuesday that friend, Michaela Kampen, had a plea for anyone who may be behind Lindsay Baum's mysterious disappearance.

"If you kidnapped her and you're watching this, if you could just find it deep in your heart to let her off somewhere so she call anyone or anything," she said.

Her mysterious disappearance has left police, family and the whole town baffled and concerned at the girl's disappearance in a town of 1,550 where everyone knows their neighbors.

"I don't really think she's in McCleary," Melissa Baum said. "Because McCleary has been torn upside-down and I just feel if she was here in McCleary she'd be found by now."

Deputies said for those outside the area wanting to help, it's difficult to find things for them to do, but police do have a message for those who live in the area:

"The biggest thing to get the message to check their areas around their home get their neighbors involved in checking the areas around the houses," said Lt. David Porter with the Grays Harbor Sheriff's Office.

He added anyone who saw anything around that area Friday evening - even something that might seem trivial - should give deputies a call. A tipline has been set up at (866) 915-8299.

Meanwhile, Melisssa Baum holds out hope a tip will lead police to finding her daughter safe.

"In my heart I know she's alive, but I need her home," she said.

And so does Lindsay Baum's dog, Cadence.

"Her dog is constantly needing attention. She knows something is not right," Melissa Baum said.

Friends and family members have planned a prayer vigil for Tuesday at 9:30 p.m. at Beerbauer Park. They're asking people bring candles and flashlights.
