Karlie Lain Guse: The Chalfant Record
A teenager’s disappearance and the changing public notices.
Abstract
California’s Department of Justice lists October 13, 2018 as Karlie Lain Guse’s Date Last Seen, under Mono County sheriff’s case 18-576.1
A Teenager in the Eastern Sierra
KOLO’s May 2022 account describes Karlie as sixteen when her family last saw her at their White Mountain Estates home in the Chalfant Valley area.4
The DOJ profile’s brief narrative gives Bishop as the place. It does not identify an original witness statement or a precise route.1
The Records Behind the Appeals
Sierra Wave’s October 15, 2018 publication carries a Mono County Sheriff’s Office update and earlier notices beneath it. These are versions of public statements, rather than separately published witness interviews.2
Inyo Search and Rescue’s own October 16 account records its participation. Its description of an operation provides a different kind of evidence from a sighting.3
Sourced Accounts and Questions
Here’s where you come in. Can you identify the original observation behind a broad place label before treating it as an exact location?1
Can you date a notice’s version and retain its qualifications when using a physical description?2
Can you separate a search team’s deployment area from a route Karlie is documented to have traveled?3
Can you distinguish the reported family-home account from a later reported walking observation, without treating repeated coverage as independent witnesses?4
Keep the statement version, event date, source and unanswered question together in a Research File in Almost Solved. A clearer source history can improve the timeline without assigning blame.

Search Work and Later Appeals
The sheriff’s update published by Sierra Wave describes a second confirming sighting near Highway 6 and White Mountain Estates, alongside helicopter, dog and ground-search deployments. It does not publish the underlying witness statements.2
Inyo SAR’s account describes aerial and ground work along U.S. Highway 6, involving several agencies. The page’s later July 2023 modification date does not establish a new search that year. Listed participants include Inyo and Mono SAR, the Forest Service and local sheriff’s offices, with aerial reconnaissance from China Lake Naval Station.3
KOLO’s May 13, 2022 report marked Karlie’s twentieth birthday and renewed appeals for information. Its descriptions belong to that dated account. It also describes an NCMEC age-progression image made in 2021. An artist’s search aid is different from a documented later sighting.4
Original witness statements and the complete investigative file were not inspected. These historical search accounts and appeals do not establish a present outcome.
Scope and Method
