KG had been living with her dad and SM since she was about age 4 so there were really no secrets here.
From very early in the case, we learned that KG was especially known to tattle on herself long before she could get in any trouble, and this incident before she disappeared was said to be very typical of KG and raised no immediate flags. These were good kids.
I recall KG, her boyfriend, and a small group were supposed to attend the football game after school but instead went to a party at somebody's house. By around 7:30 pm, KG called SM and tattled on herself that she didn't go to the game and asked for a ride home. And the first thing KG did when SM arrived to collect her was to tell SM that she had smoked weed. Since this (Oct 12) was early in the school year, KG felt bad for breaking her promise to stay clean and failed in the first school quarter. (It's not been reported how long KG had been clean before she used weed on this fateful night).
By all accounts, nothing about school or the evening including the weed use was considered to be out of the ordinary for the family dynamics. And more importantly, the other kids including KG's boyfriend corroborated the same details about the night, and nobody else except KG reacted differently.
Also, I'm not recalling reports of any diagnosed "mental problems" or concerns about KG's mental state other than typical 16 yr old teen angst, whether or not her parents would allow her to get a driver's license -- especially since they'd just moved to a new development outside of Bishop. IMO, I also think there was some angst about how long she'd have to wait before receiving approval to return to Bishop HS. I know the link I posted up thread cites KG was attending the Alternate school to improve her grades, I also recall this was a decision made at the end of the last school year by the School Administration when the kids were caught smoking in the restroom.

Crimeonline's article of 10/25/2018 linked below is probably one of the better sources of
early info as we first learned it -- before everything (including SM as the family spokesperson) went to private FB groups (not approved here), and/or the machine took over to rewrite the facts that perhaps would be more acceptable to what at the time, was probably considered a critical public.
It’s been almost two weeks since a 16-year-old girl disappeared from her home in a small California town, and her family is desperate for her safe return. Her mother Lindsay joined “Crime Stories with Nancy Grace” on Thursday to express her fears over what may have happened to her daughter, as...

Karlie Gusé, 16, reportedly disappeared from her Mono County home on October 13, somewhere between the hours of around 5:45 a.m. to 7:30 a.m. The girl’s stepmother, Melissa Gusé, told CrimeOnline she picked Karlie up the night prior in “town,” miles away from the family’s rural home on the outskirts of Bishop. Karlie was then brought home, according to Melissa, near White Mountain Estate Road in Chalfant, which lies around 14 miles north of Bishop.
Melissa told CrimeOnline that her stepdaughter admitted to her that she had smoked marijuana on the evening of October 12 while out with her boyfriend and a few friends, and said the teen seemed disoriented and “acted paranoid” when she picked her up at around 8 p.m. The stepmom, who said Karlie was alone when she picked her up, stated she eventually she got the teen calm and even slept in her room with her all night to make sure she was OK.
At around 5:30 a.m. the following morning, Melissa reportedly woke up and when she looked over, Karlie was next to her, lying awake. At some point, Melissa dozed off again for a short period, then woke up again at around 7:15 a.m to 7:30 a.m. and Karlie was gone.
There were no signs of forced entry into the home and the front door, according to Karlie’s biological mother, Lindsey Fairley, was slightly ajar.
ETA: Reportedly, SM took a video of KG at home during the evening before KG disappeared that she intended to show to KG as confirmation of her squirrely behavior after the weed indulgence. To my knowledge, nobody has seen this video to be able to independently report on it. I recall KG's birth mother offering that there could have been a scuffle at the end of the video but it's not been confirmed here.
Lindsey indicated that the recording ended before she could determine if there indeed was some sort of altercation, but it left her feeling bewildered and worried. Lindsey is now pleading for help and hoping someone, somewhere will come forward with information.
