CLEARLAKE, Calif. (KTVU/CNN) - The family of a missing California girl are holding onto hope she can be found alive.
Nine-year-old Mikaela Lynch, who has autism, disappeared Sunday while vacationing with her family in Clearlake.
A CDF chopper was launched Tuesday morning to search from the air, while sheriff's deputies used boats to check the docks along Clearlake.
In the meantime, there were dozens of searchers who went door to door in the neighborhood, all of them looking for any sign of Mikaela, missing since Sunday.
Her godfather, Mike Dowling, says the family is trying to remain positive.
"Obviously this is a very difficult time for the family, for the parents especially. We are eternally grateful for the volunteers, the law enforcement, and the people who have come out, the community. The family remains hopeful at this time," he said.
Mikaela is autistic and unable to speak. She and her family were staying at their vacation home in Clearlake when the girl wandered off on Sunday afternoon.
Authorities say she was playing on the trampoline with her brother and her parents left her alone for just a few moments. The Clearlake police chief says there is surveillance video from a neighbors showing Mikaela running away from her home.
"It shows she was alive and well at a specific time and heading in a certain direction, so we're able to focus our search dogs and scent dogs in that area which can lead us to other areas," said Chief Craig Clausen.
A command center has been set up at a church and searchers have come in from a number of different counties to help find the little girl.
Neighbors are also pitching in. Jeanette Wilson was passing out flyers and keeping her eyes open.
"Here I am and hopefully we find her. We just got to keep praying that she's okay and she's safe and that she gets returned home," said Wilson.
Mikaela's family is asking people to check their yards and around their homes because she is known to curl up in a comfortable place and stay put.
