Underwater Forensics

by Ryu

***This is an important post for some WNs.***

Throwing guns, knives, cars or bodies into the water is no longer any good. A new, highly specialized area is here: underwater forensics. Underwater crime scenes can be worked in the same way as a terrestrial one now.

With a knowledge of currents and tides on certain days, one can put a range on where an item might be. Cars and guns have been found in this way, even years later.

Metals DO rust underwater. But not enough to eliminate all evidence. Guns recovered from underwater still have the characteristic lands and groves in the barrel, even after long submersions. An acid solution usually can cut down a thin coat of rust.

Many bodies of water, such as NYC’s East River, are scrubbed regularly for weapons by divers and boats.

Underwater forensics is a rare specialty. Police divers are relatively common. There are a few thousand in the USA. But true UW forensic detectives there are only ……….a few hundred in the entire country; one find them in big cities and big agencies.

That will do as a broad introduction. There are many little details. Civilians underestimate distances by water. Police divers work by touch. Collecting a corpse underwater requires a sort of large, porous body bag.

Things tend to settle pretty quickly, even in fast-moving bodies of water. Most bodies surface due to decomposition gases, no matter how well weighted-down. Underwater items will retain prints for awhile.

It will be interesting to see if the USG can sustain their growth in forensics. No third world country can afford a first world forensic technology. It takes alot of money, training, and the right population to learn it.

  1. Thanks Ryu. You are becomming an expert in analysising out enemies’ “crime” solving capabilities. We should think of a title for you and the field.

    I was surprised that fingerprints remain after being plunged underwater but I guess I shouldn’t be.

  2. Reminds me of Uncovering the Secrets Beneath the Surface of the New York Harbor.

    Most interesting was:

    “Surveillance Systems: The U.S. Coast Guard operates anti-swimmer sonar systems, which are moved around as they’re needed in the harbor. The gear pings signals out, and displays hits—indicating unidentified people or boats—on a video screen. The Coast Guard also does pier sweeps: “If someone puts something on a piling”—say, an electronic device we find it.”

  3. “No third world country can afford a first world forensic technology. It takes alot of money, training, and the right population to learn it.”

    For the most part they won’t be able to afford it very much longer. That is, they won’t be able to use it on everyday crimes, which will be good for any kind of rebels. These kind of detailed forensics will only be used when some elite ‘misplaces’ their toy poodle or one of the help has run off with the silverware. Crimes against proles or even the enforcers will not elicit this forensic response in the future.

    IF there were any actual physical resistance in even marginal numbers, the forensic system would be overwhelmed anyway and the enforcers wouldn’t even bother with it anymore. (besides in a real rebellion the forensic teams would be prime targets and most would find another profession if that happens.) The enforcers would simply fall back on the tried and true method of just rounding up the most likely suspects and throwing them in detention camps or lining them up against a wall. At the end of the day, they are lazy and will take the path of least resistance. All they are really concerned about is collecting a nice cushy pension at the end of the day and anything which will make that happen is fair play to them.

    • The forensic system is already overstretched, even without any resistance, look at the rape dna sample backlog, or no such agency drowning in unprocessed data. The courts are completely overloaded as it is, the systems only grinds somehow along because 90%+ cases end in plea bargains. That’s why they are doubling down on thought crimes, you don’t need forensics to burn witches!

      A lawyer on a podcast recently even joked that one should immediately claim to be transgender when arrested, go to court in a dress, because no one dares to convict a bearded lady! That was referencing a case where a transgendered man stabbed someone, but wasn’t convicted, the other guy defending himself was! And of course Caitlyn Jenner Avoids Manslaughter Charge in Fatal Malibu Crash…
