A National Guard helicopter joined the search Monday for Lindsey Baum who vanished when she was in downtown McCleary between 8:30 p.m. and 10 p.m. Friday, while walking home from a friend’s house.

“Each hour that goes by, I am starting to get more and more panicky,” said Baum’s mother, Melissa Baum.

Missing McLeary girl Lindsey Baum

Lindsey wanted to spend the night at a friend’s house about six blocks from her own home, but her friend’s mother, Kara Kampen, told her no.

“I told her no you can't spend the night. If I had said yes you can stay the night, she'd be home now,” Kampen said.

Investigators monitored Lindsey Baum’s MySpace page for any clues but said the account has been inactive since she vanished and she left no posts indicating she was planning to leave.

"There was nothing that indicated any preplanned intention for her to run away or go anywhere," said Grays Harbor County Undersheriff Rick Scott.

Searching the Wildcat Creeks on Monday, the Thurston County Sheriff's Office dive team didn’t find any signs of the missing girl. Other officers took the contents out of Dumpsters making sure nothing goes unsearched.

"With the time that's passed now, it doesn't look good," Scott said.

Searchers said the route Lindsey would have taken from her friend's home to her own home is short and direct. Police said the girl was unlikely to get lost.

“We're convinced somebody took her," Melissa Baum said.

Scott said his department is not yet ready to conclude that Lindsey was abducted because there is no evidence to indicate that's what occurred.

On Sunday, police and FBI stopped cars traveling through town hoping to find anyone who may have seen something.

Police said the key to finding the 10-year-old girl may lie with anyone who saw the girl as she walked home in the small town of McCleary.

“I know she's alive. I know some people are thinking I'm crazy, but I feel it in my heart that she is still alive,” Baum said.

Volunteers have been handing out fliers to motorists and circulating them throughout the county. Search and rescue teams will still search throughout Monday night and continue to knock on doors.
