FBI Overwhelmed With 'Solutions' To Encrypted Note 137

Posted by timothy from the hey-bub-you-asked-for-it dept.
An anonymous reader writes "Recently the FBI asked for the public's help in solving the encryption in a note linked to a man's murder. Well, they got so much 'help' it has overwhelmed the agency's phone and email systems. Dan Olson, chief of the FBI's Cryptanalysis and Racketeering Records Unit (CRRU), urged potential code-breakers to send their tips via mail rather than sending emails or flooding phone lines. 'We don't have the bandwidth to handle the emails we're getting,' Olson told FoxNews.com on Thursday. 'We're getting a bunch [of responses].' Suggested solutions range from a list of the dead man's medication schedule to instructions from a computer repair technician: 'He is speaking to a computer tech on how to fix his computer,' one message read."

      I checked out the reference (since removed, oddly) that people who are bipolar often keep long-term records of medication schedules and effects (page 2) and historic record of major 'episodes' (page 1) so that they can use them to try and build a personalized medication schedule over time on a bipolar support forum, and it checks out. It's also true that people with bipolar disorder are encouraged to keep them secret, and so would be like to keep coded versions of these notes in case they were found.

      I'm bipolar and we are told to keep such logs in short-hand because, though we are protected by laws, we are told to stay in the closet, because so many violent crimes are caused by bipolars. If we just came out of the closet, people might realize that those of us who are medicated are fully functional and safe. And we are 2 to 10 % of the population, possibly from recent environmental and stress related aggrevators. But it does take very detailed traking to get our medication right and knowing the triggers is key: week days might relate to work triggers, months to seasonal disorder and times of day are critical to knowing when to take meds and how much. The nature of this note suggests that he is having an episode and is thinking faster than he can write.

      • Some of that does seem to fit, but I think it's a stretch in other areas. Documenting back to 1974, 1971, etc, in that detail on the spur of the moment is highly unlikely. If keeping records is that important then that information would have already been documented, and not jotted down randomly at a whim 30 years later. Those numbers (74, 71) likely have another meaning. The 3XORL fits with taking a med 3 times orally, but I'd think someone that into prescription meds would use actual medical terminolog

I'm sure some do that, but he makes it sound like that's commonplace.

          There was no part about that, so no wonder it's far-fetched. There was a part about bipolar people suffering prejudice due to some violent crimes, and using codes to prevent anyone who sees them jotting stuff from realizing they're bipolar.

        Seroquel wasn't approved by the FDA until 1997, and Serenace I can find records of only as a drug used internationally for animals... although its primary ingredient, haloperidol, was FDA-approved in 1967 or so as the drug Haldol.

    My girlfriend is about 5’7”, weighs around 130 and has brown hair and brown eyes. She is white and while she’s not fat, she is a tiny bit overweight. She has a huge round butt which is very soft.

    My first experience with it was in the forest on a walk, she let me kneel behind her and put my nose in her jeans-clad butt to sniff it for a few seconds. She got nervous stopped.

    Later, she farted on the couch- It was a small rip, and she stood up so that I could sniff it. It had hardly any smell to it, and she looked embarrassed. Later still, she stopped on the stairs with me behind her and let me put my nose between her cheeks again. I felt her pushing to try and fart, and I felt a tiny bubble, but it didn’t stink. At night, she sat on my face in jeans and rubbed her butthole over my nose. I could smell a fart, but I didn’t hear it. I also followed her outside when she told me she had to fart and knelt behind her and buried my face in her jeans. She let out a five-second silent fart, and I sniffed- It was weak, but still very eggy.

    The next day she woke me up and sat on my face for about 5 seconds in her pajamas, which where pink and very soft, letting my nose press up against her butthole and her cheeks spread over my face. I sniffed, and it smelled slightly like rotten eggs. Later she told me that she had farted just before she sat down. Later in the morning she told me she had to fart and lifted up her butt off the couch. I knelt down and put my nose under her raised cheek, which wasn’t high enough for me to get my nose to the source. I heard a long rumble and I sniffed, and It smelled earthy and eggy. She did another quiet one that I sniffed like that for about 30 seconds. She went to the bathroom and let me smell the air afterwards. It smelled eggy and poopy, and I stayed until the smell dissipated, which took about 10 minutes.

    The next day, we went to a store for nerdy things like DnD and other such stuff. While there, I heard her rip a quiet fart. I stayed in the area and the terrible eggy scent wafted up to me, and lasted about 30 seconds. She was embarrassed to fart in public. She did another in a jewelry store, but it was silent. It stunk just as bad, and I think the person working smelled it.

    Later, she decided to play some video games, and while she was playing I would sniff her butt every now and again. She said she had to fart, so I picked up a stuffed cow and she sat on it and let it rip quietly. I sniffed it, and it was eggy and trapped in the fabric. she said “Does it smell good?” I offered her the cow, and she sniffed it and made a face of disgust. Once when I was sniffing, she ripped a very stinky fart that smelled like rotten eggs and onions- It was a two parter that went Bluurp bruuuunt- and I sniffed it from her jeans. I told her how stinky they were and she laughed. Then I felt her clench her cheeks, and a quiet but very bubbly fart came out and she said “I did another one!”

    When we were in the car, she would fart on my hand and then let me sniff it. Once after Italian food, she rolled up the window and ripped a loud raspy one. The whole car filled up with an eggy smell, and she said “Don’t look at me after I fart!”.

    She gave me a good face-fart in her pajamas- She
    Stood in front of me and I twisted so she could sit on my nose. She sat and spread her butt cheeks apart and ripped a silent fart that stunk of eggs. She let go of her bottom and her asscheeks spread over my face, sealing my nose in her stinky fart. It was even more intense when she let her butt spread over my face, it smelled three times as bad. She did another one a few minutes later and it was even longer, and I could feel the heat on my face. At the end, it made a rasp, low-pitched squeak. “Did you hear the squeak?” she asked, as she settled her butt over my face.
    She ripped a terrible one on the couch- She was mid sit when she stopped and let out a four-second series of juicy pops and cracks.
