Karlie Guse Update: Mysterious Details Emerge In California Teen's Disappearance

Details about the mysterious circumstances surrounding the disappearance of California teenager Karlie Guse emerged Wednesday. According to the 16-year-old's family, the girl got frightened on Oct. 12 -- a day before she went missing -- after skipping a local football game to attend a gathering with her boyfriend.

Her stepmother Melissa Guse recalled that the teenager had called her and asked her to pick her up from a location. When Melissa arrived, Karlie had already left and was running on a dark road. On the way back home, Karlie said she was worried that the vehicle Melissa was driving would kill her. She moved seats several times.

Once home, according to testimony given by her father Zac and Melissa, Karlie continued to express fear and referred to the lettuce in her salad as the “devil’s lettuce.” Her parents said that the girl had hugely dilated pupils, according to Fox News.

The news outlet also reported that the teen’s stepmother had recorded her voice, which sounded disorientated. Melissa allegedly wanted to be able to show her stepdaughter what she sounded like under the influence. However, that recording, according to private investigator Michael Boone, was the last time Karlie's voice was heard before she vanished.

Guse said Karlie’s behavior fluctuated between paranoia and excitement.

“From Friday evening to Saturday we had several texts. I told Donald ‘please pray’ one time,” Melissa wrote to Fox News, without referring to who Donald is. “Karlie was talking about going to church and wanting to read the Bible.”

The parents kept checking on the girl in the early morning hours but later found she was missing. They found a footprint, believed to be the girl’s, in the driveway. She is 5-foot-7-inch, 100 pounds with blue eyes and blonde hair.

“It has been seven months,” her biological mother, Lindsay Fairley, told Fox News. “At 9:35 a.m. on Saturday, October 13, I was notified by her father — my ex-husband — that she was gone. Gone to me is a huge red flag and it has never sat easily with me.”

Three separate witnesses confirmed having seen Karlie that morning exhibiting strange behavior. The last documented sighting was of Karlie walking toward Route 6 in California, which stretches all the way from California to Massachusetts, through 14 states – by way of Nevada to Nebraska, Indiana and then New York. With no immediate indication of abduction or physical description of a vehicle, no Amber Alerts were sent at the time.

“There isn’t anything, we have followed every lead," Sheriff Ingrid Braun of the Mono County Sheriff’s Office said responding to the case, local media reported. "It is super frustrating. It’s an open investigation until Karlie is located.”
