Dating back to December 31, 2015 Redditor KnightofSunlight posted a mysterious photo to r/WhatsThisThing---the forum that asks the internet help for identifying unknown objects. Fast forward a bit and the thread determined that the photo this dude uploaded was actually a land mine, and that he'd been inactive for a long time; and that's when the sh*t really hit the fan.
Some folks were quick to speculate that what they had on their hands was a man who had potentially died by landmine-suicide, and that this was his morbid goodbye. After about a month of painful silence, an investigation was mounted by the subreddit, Reddit Bureau of Investigation. Little was discovered besides the fact that the original poster lived in Redding, CA; AND that he was possibly moving to Ecuador where land mines aren't uncommon (further fueling the stress). The story lost steam after that, except for the occasional AskReddit thread when someone would ask about the creepiest/unsolved thing to happen on Reddit.
Through some serious sleuthing, Electronic-Dad managed to connect KnightofSunlight to a user of a gaming forum and Steam account, which was located in Redding, CA, no less.
KnightofSunlight went and posted a list of banned userIDs to the gaming subreddit r/7daystodie. Even though the list is now offline, Electronic-Dad 'google searched' the image link which led him to another user named 'Stupid' using the same link, posted just a day before the Reddit thread.
Both located in same location in Redding, CA.
HOWEVER, Electronic-Dad did tell them that he got in touch with Keystone Knight who sent him the picture above.
They were planning on confirming Electronic-Dad's sleuthing, who actually did respond saying that he was the epic troll who posted the original photo of the land mine! Wow is right. WOW.
He also said that he sent the photo to Electronic-Dad and that he burns his accounts at the end of the year. It's just he had no idea how obsessed Reddit would get with that particular photo he uploaded before going off the grid with that account.
