KN, p. 222 “Underwater Evidence and Body Recovery: Lakes and Bodies”

 

Warning: article contains details about dead bodies.

Crime scene tape has been posted around your favorite big pond or lake and nobody can get on/in the water until it has been searched. What has happened? Perhaps a body has been sighted underwater by a swimmer, or a fisherman has snagged something suspicious on his hook. A violent crime may have been committed in the area and the police are looking for discarded weapon(s). Or a report has come in to the police station about a missing person, and that missing person may have been seen in the vicinity of the water. Law enforcement is already on the case and if the crime scene tape is up, along with officers conducting an investigation, then a dive team is most likely working your formerly peaceful spot.

 

The USA has a great many lakes and assorted other bodies of water, both natural and man-made. Just a few examples:
 

Alaska: over 3,000,000 lakes (yes, 3 million)

Minnesota: 10,000 lakes (it’s even written on the license plates)

New Jersey: 366 named ponds, lakes, and lagoons

North Carolina: 78 named lakes as well as several bays, sounds, and hundreds of ponds.

Texas: over 200 large lakes and reservoirs.

 

When that many bodies of water are part of the landscape, it makes sense that the Sheriff’s Department (County law enforcement) and First Responders have teams that specialize in underwater evidence and body recovery. Why the Sheriff’s Department? It’s not about deep pockets financing the operations, it’s all about jurisdiction and best use of available resources. Many large lakes cross town lines, and the Sheriff’s Department has jurisdiction in all the towns in its County. No need to duplicate personnel, when prevailing thought is that one or two teams per County will be able to handle the job of underwater evidence and body recovery.

 

Note: the local Fire Department usually has a First Responder team on the site of any accident – they are trained for rescue. At some point, it will be determined whether it is a recovery or a rescue and/or if there is a need to preserve evidence. It’s usually a recovery rather than a rescue at a lake, because after a person spends ten minutes under the water without air, it becomes a recovery operation.

 

Are there enough on-the-water deaths to make certified-for-recovery dive teams necessary? Sadly, yes. The Great Lakes Surf Rescue Project tracks those stats for the five biggest USA lakes. There were 99 deaths reported in 2016, 88 in 2017, and as of this writing, 47 so far in 2018 in the Great Lakes alone. North Carolina has reported 10 lake deaths so far in 2018.

 

Most of the time, the lake deaths are accidental, but on occasion, bodies are found because of a homicide.

 

A body will float after 72 hours, and continue to float for a couple of days. After that, the naturally occurring body gas is expelled and it will sink again. Bodies are often found fairly quickly, but a body gets like jelly if it’s been in the water for a while, complicating the collection process.

 

Cold water will preserve a body, and warm water will cause more rapid decay, so divers must work carefully in the warmer locales. Cadaver dogs can pinpoint the location of a body to speed up the work. It’s been discovered that the longer the body is in the water, the wider the smell arc for the dogs. It’s a little like a dead fish smell, more concentrated closer to the body.

 

If no cadaver dogs are available, the divers swim in ever bigger arcs from the chosen starting point onshore and they work in grid patterns. If the search area is large enough, one of the onshore/on boat team members keeps a map/record of the searched areas.

 

In general, when working in shallow water, the investigation and recovery can be accomplished by dive teams alone. In deeper water, it will be a combination of boats and dive teams that do the search and recovery.

 

Most dive teams have the same equipment. They dive with aluminum scuba tanks and 3200 pounds of air will last about an hour. The basic dive suit is worn for warmth and protection – below 10 feet, it’s cold, no matter what the weather is up top. They also have hazmat suits to dive with in toxic environments.

 

Buoys are color-coded and are released to show when the diver(s) need help or when marking the spot.

 

With the smallest team of 3 people, there are:

  • Diver
  • Safety diver
  • Surface tender

 

With a team of 11 people, at any given time, there are five people in the water.

 

It is protocol to always keep one diver on the surface, ready to assist under water or switch places with the diver already in the water. The “tender” stays on the surface (whether in a boat or on the shore) and directs the search using a rope. The tender signals by tugs; he/she lets the rope play out, and then gives more when needed.

 

The “tender” not only controls the line and the search pattern, but keeps track of the air time and the clock time on a log, which becomes the official record of the diver/search activity. If there is a new diver on the team, the tender tracks to see the average air use, an important stat to have when making sure a sufficient supply of air tanks is on hand for each team member. The tender can estimate the time/air left in the tanks in use after observing the previous pattern of intake by the newbie.

 

After spending time in the water, the divers will be dehydrated, another thing the tender keeps track of.

 

 

Stay tuned for Part 2: “Searches.”

KN, p.174 “Death by Swimming Pool”

 

Pool-JWWaterVolleyball copy

Sheila and I watched a British TV show the other night that included a ‘death-by-drowning’ scene. The wrong person wound up dead in the pool in this mystery because of an identity mix-up. By coincidence, the very next night, an old movie featured the same cause of death. We began to wonder how often death by drowning actually occurs.

 

While no stats were available specifically concerning murders caused by drowning, the general answer is that an average of about 10 drowning deaths happen every single day in the USA. It’s actually a huge problem worldwide, not just here, and is among the top five reasons for deaths. A 2014 report from the World Health Organization (WHO) stated that about 372,000 people died in 2012 from drowning. This number excluded deaths by vessels capsizing, natural disasters, or intentional drowning deaths (suicide or homicide).

 

http://www.who.int/violence_injury_prevention/global_report_drowning/Final_report_full_web.pdf

 

Surprising as that number might be, the Centers for Disease Control (CDC) in the USA lists an additional alarming fact – that nearly 20% of the people who die from drowning in the USA are under 14 years old. Similar information exists for the global stats cited by WHO. Plus, for every child that dies, there are several others who have to get treated for their injuries in the water.

 

But before you jump to the conclusion that the injuries are all happening at home pools in the USA, think again. About 47% of those who had to get treated were swimming at a home pool, but a full 27% of the swimming injuries happened at a public watering hole.

 

Then there are the drowning deaths, still accidental, but pushing the limits of that definition. A recent story in the news involving a controversial SEAL training death points to a seemingly universal opinion that we are indestructible, that swimming is at best a risky enterprise, but that people in good shape can survive with less oxygen getting into their lungs on a regular basis. Hmmm… not true. Even great swimmers get tired and can drown.

Lots of private pool owners swim alone. Why not? The pool beckons on a hot day and it’s a relaxing way to cool off. But, what if you are tired at the end of a work day, and slip on the edge of the pool, knock your head on the way in and… if you are alone, nobody is there to pull you out of the water or to call 911.

 

That may be what happened to a guy who was found floating in his pool back in April.

So, what can you do to stay safe in the water?

 

  1. Don’t swim alone.
  2. Make sure that your children know how to swim.
  3. Don’t allow your children to swim unless there is an adult with a phone present.
  4. If you have a pool, fence in your yard.
  5. Be aware of ocean water dangers – undertows, etc
  6. Wear a lifejacket when boating on a lake or in the ocean.
