DENVER — California authorities say a missing and endangered 11-year-old girl may be in the Denver metro area.

Kaia Fina of San Clemente, California was last seen Thursday night; she was reported missing Friday.

Authorities say it is possible that Kaia’s biological mother, Sera Fina, may be with Kaia in a black 2007 BMW X3, with California license plate number 7RRY771.

The Orange County Sheriff’s Office tweeted Monday night that they believe Kaia is now traveling with Sera in Colorado, near the Denver Metro area.

Kaia's father, Philip Gregory, told Denver7 the family is convinced that Kaia and Sera are in the state.

"The whole family believes that she’s with the mom. They’re in Colorado. An 11-year-old girl didn’t magically go there by herself from San Clemente, California. So just to be vigilant, and I know that she’ll be seen and/or make a mistake," Gregory said.

An Amber Alert has yet to be issued for the missing girl.
