Sesseur (real name Jeff Case), the author of Jeff The Killer was recently exposed after an intensive investigation (conducted by the same people who have, for years, tried to find the unedited JTK image, with an 11k bounty for the person that does) with
an over 10,000 word document that details some things such as:
-How Jeff was involved in the grooming of a 13 year old fan of his work by directing her to his pedophile brother Brandon, fully knowing what he was doing and to this day, continues to direct JTK fans to him. He has recently threatened to take the victim to court over "lies"
-How Jeff downplayed the actions of an incident involving his brother, in which he violently attacked two of his cousins. Before and after the incident, Brandon had showcased a history of violence and owns firearms.
-Brandon's autistic fixation with the North Hollywood shootout to the point where he has cosplayed one of the atackers and tried to make a shitty video game based off the event
-Brandon's fixation with cults and extremists, even including a lengthy and disturbing manifesto regarding his thoughts
-Jeff and Brandon's severe drug addiction, which has been potentially funded by copyright fraud related to the Jeff The Killer image, whose author is currently unknown. Jeff has many times falsely (and poorly) claimed to be the creator of the image and has gone as far as to make merchandise (such as costumes) of it and even sold the rights (including the visual depictions) to different companies
