Rescuers are searching the mountains near Big Bear Lake for a missing Irvine woman whose snow-covered car was found near a trailhead Sunday morning.
Lisa Ann Cimbaluk, 35, was last seen at her Irvine home the morning of Dec. 29. She did not tell her family where she was going but "there are no signs of foul play," said Farrah Emami, a spokeswoman for the Irvine Police Department.
Her family reported her missing Dec. 30.
Sheriff's deputies spotted Cimbaluk's vehicle early Sunday, Jan. 4, parked at the Woodland Trailhead in Fawnskin, a small community north of Big Bear Lake, covered in snow.
"Deputies and volunteers searched the area yesterday for the missing woman and are very concerned due to the overnight temperatures in the area," said Jodi Miller, a San Bernardino County Sheriff's Department spokeswoman.
The National Weather Service recorded overnight temperatures dipping as low as 1 degree Fahrenheit in the Big Bear area since Cimbaluk disappeared.

I only met her a few times, but she is the daughter of one of my mom's coworkers; a few years older than me. From what I know about her, she has struggled with depression and other mental issues for many years, and has always had a bleak outlook on life. She doesn't own a cell phone, and didn't tell her parents where she was going. She's a sheltered Irvine kid with no wilderness skills, so unless she's been holed up in a cabin up there, I doubt she's still alive.

It wouldn't surprise me much if she went up there without the intention of coming back.

The world is a strange place.

Mental illness can be tough. Hope those parents don't blame themselves. Best of luck.

I'm sorry to hear that...the best we can do is hope. But hey there's always hope, a lot of people go missing in this kind of situation and come out alright. Hang in there and be strong

I hope one of two things happened

A) She went out there with the purpose of killing herself, and did so quickly, or

2) She's been safe in a cabin.

Wandering around in the mountains with no protection, food, etc, is a terrible way to go.
