Berreth’s family wrote on the Facebook page that it would be out of character for the mom to leave without warning, despite her pilot experience.
‘She does not own a plane nor do we know of any local friends that she would borrow one from,’ a Facebook post said.
‘I don’t believe she has ever made a flight without filing a flight plan. We do realize that it is possible to rent a plane, but I believe someone would be missing it by now.’

Cheryl joined the Woodland Park Police Department for an emotional press conference asking anyone with information about Berreth’s whereabouts to come forward.
Police Chief Miles De Young said the department is working with the Colorado Bureau of Investigation, the FBI and authorities in Gooding, Idaho.
He said no suspects have been identified.
All planes at Berreth’s place of employment have been accounted for and there is no evidence that she flew anywhere.
De Young said that Frazee was invited to the press conference, but decided not to attend. When asked why, he said: ‘That’s a question you would have to ask him.’
The police chief said Frazee is cooperating with investigators and is currently watching the couple’s young daughter.
Cheryl told reporters: ‘I’d just like to talk to you a little bit about Kelsey. She’s not the kind that runs off. This is completely out of character.
‘Kelsey loves her god, she loves her family and friends, and she loves her job. She’s reliable, considerate and honest. … She doesn’t run off, and someone knows where she’s at.’
