Comprehensive List of Fake Mockups
Compiled by pat64wizard
The images in this document are compiled for the Jeff The Killer original image lost media search. This document is intended to archive every possible mockup/fake image to avoid future confusion. Additionally I may include evidence to prove that images commonly mistaken for the original are not the case.

The following pictures are the ONLY two original Jeff the Killer images:
JTK1 JTK2
Anything resembling them has been fake or debunked unless confirmed by the JTK discord
MOCKUPS START DOWN BELOW ↓↓↓↓
Famous Mockups (All of which are fake):
Image of a toddler which was confirmed by the discord user who created it
This one is fake, debunked by user Dark_Angel_Ra in this reddit post: https://www.reddit.com/r/OriginalJTKImage/comments/1dd98y3/debunking_mockup/
Infamous “Katy Robinson” photo, debunked here:

Infamous “green eyed jeff”
AI Generated Mockups (And photoshops)
(Most people saw this image in the gooseboose video), but this was AI generated and confirmed by the creator.
Creator’s original reddit post is deleted, but Blameitonjorge’s tweet confirming its fake still remains:

This one was created by Brandotistic, it was then stolen from the discord and posted online.

More AI generated (The colorbars in the bottom right are a watermark of Dalle AI software)
No, it’s not an anime girl either
(Confirmed by the creator, made with stable diffusion https://www.reddit.com/r/lostpause/comments/106tc2g/i_turned_jeff_the_killer_into_a_cute_anime_girl/)
The rest of this section consists of tons of AI mockups and bad ones, feel free to skip it on the sidebar if you get the gist
Moooore AI generated images
So many AI images
This one’s just really bad
^^^This one is Mariko, more on her later
GPT has been getting better. This more realistic image is still debunked by its creator

Debunked Images
More unrelated women
Overly attached girlfriend
Reiko Takamura
It’s not Orie Chef either
Kalle Havumaki debunked (His mouth has tricked many people)
Yellow Jeff sometimes referred to ask “JTK3”, another famous edit of the image, isn’t actually a mockup but an edit to make it look scarier. The teeth are from google images, while the rest merely has a filter.
From Byonabi (byokan sunday), turned out to be a cosplayer at Tokyo Big Sight. Not the original

Currently Standing Leads (But Debunked Images)
This section shows identities who are still possible candidates for WHO is the JTK person, but the PHOTOS being spread are incorrect/fake mockups. Just because these people are included doesn’t mean they cannot be JTK, just that the IMAGE shared is not the one we are looking for:
Sonoko (Many consider her a still ongoing lead, if other images resurface they may be found in the Sonoko search document: https://docs.google.com/document/d/1o0T4aY_l97KJr_vBftoKJhjq0ygrmqdDNUDQlCFyZJY/edit)
Koge, (Another still possible identity), a net idol under investigation with a document linked down below, if you would like to see her photos. Any posted photos in the documents are probably debunked so far.
https://docs.google.com/document/d/1gtjEotXBT2YW_yM6oYvvJMDiyoBAme5ABOSDDZdksP0/edit
Mariko/Suzaku
In my opinion, the most possible lead so far, an uncanny resemblance to the JTK original image.
It is definitely possible that she is JTK, however no images found yet resemble it enough.
← MOCKUPS
This Mock-up above has been making the rounds lately on the internet, but it is clearly fake and shows Mariko’s face directly shopped onto JTK1.
Some other images like the one pictured above have been created to showcase what Suzaku (her old boyfriend)’s room might have looked like related to the JTK image. These are mockups as well and shouldn’t be confused with the real image.
A comprehensive document of all the Mariko information found is linked below, please consider checking it out if you would like to help out with the search.

Conclusion
Obviously, there are MANY fake mockups, since they are so easy to create especially with AI image software like DALLE. The reality is that they do not add anything to the search and generally slow the process down. AI has gotten more and more accurate as of 2025, where people are becoming unable to tell the difference between what is generated and what is an actual photograph.
If you find a picture or come across something that looks interesting, do not spread it yet, first ask the discord and as a collaborative effort the team can help look into the pictures to confirm where it comes from. This would make the search much more efficient and help the process.
Where it stands right now, we have enough images proposing what the original JTK “might have looked like”, so it is unnecessary to create more mockups.
