23 Comments

Three men were found dead inside a tent in a forest in Isumi City, Chiba Prefecture, on Monday morning.

Police said the men had gone into the mountains on Sunday to go duck hunting, Sankei Shimbun reported. An acquaintance, looking for them, discovered the trio collapsed inside their tent around 8:30 a.m. on Monday.

The three men, two in their 70s and one in his 60s, were confirmed dead at the scene by firefighters. According to the fire department, the group appeared to have died in their sleep.

The men had no visible injuries, but a kerosene heater and lantern were among the equipment discovered. Investigators suspect that the three may have died from carbon monoxide poisoning.

Suicide?

Did they have any hunting equipment? Or any spent shells etc

This time of year is great for duck hunting, I usually go for a few days every winter, but you need to collect any shells or cases afterward as per the Japanese laws. If there weren’t any then suicide could be suspected.

Tragic. CO2 poisoning. The silent killer.

It looks like carbon monoxide poisoning, the easiest way to confirm this mysterious deaths, would be send the heater to a lab where it can be tested for gasses when lit. I will presume there will be blood tests or an autopsy on these guys just to confirm.

CO2 is Carbon Dioxide, Carbon Monoxide is CO.

@Harry. Some people confuse Mono and Di

Heard of this happening before the old kerosene heater in the tent go to sleep never wake up very sad story not a way I would like to go.

Sad, but not that uncommon, to be overcome by carbon monoxide. I am a bit surprised that the tent did not leak enough fresh air in to keep them alive.

foreignbrotherhoodarmy. That's amusing, instructing the police detectives to perform the most rudimentary element of investigation.

Rest in Peace gentlemen. It is odd that this would have happened. If they had gone tent camping before, they would have known of the risk of CO poisoning.

"Heard of this happening before the old kerosene heater in the tent go to sleep never wake up very sad story not a way I would like to go."

A very peaceful way, actually. They didn't feel a thing. They just went to sleep. RIP.

How about drowning? Or getting sucked down a drain pipe and THEN drowning?

Sleeping sounds like the BEST way to go!

Carbon Monoxide is CO poisoning.

The 2 on CO2 would make it Carbon Dioxide.

Carbon monoxide is heavier than oxygen. If you plan on using any combustion-based heat source in your tent, buy a tent with vents along the bottom edges. Most newer model compact tents only have vents on the top, it can lead to a false sense of security.

You don’t have to collect “all”of them, just a reasonable amount so the cops know you are using your gun, and not stockpiling. Score cards from a target range will also suffice.

I see shot shells littered all over the mountains around my house.

This time of year is also deer and boar season. Happy hunting!

That is sad. It was probably just carelessness and carbon monoxide poisoning.

That could lead to a false sense of security too.

Carbon monoxide is indeed heavier than oxygen but is lighter than air whch is what is usually around us.

But even if its lighter than air it doesnt just rise because the difference in weight or density is very small.

Instead CO mixes very well with air which makes it very dangerous

I am not sure on what are you guys basing the statement that "carbon monoxide is heavier than oxygen", but under standard conditions its density is lower than oxygen.

usually tents are well ventilated, but being winter, they probably went for a tight one, and used the heater to keep warm during the night. rip

Thanks for the correction i didnt even consider that its incorrect, just want to point the fact its not oxygen and carbon monoxide thats mixing inside the tent but air and CO

Carbon monoxide is heavier than oxygen. 

I'm fairly sure carbon monoxide is slightly lighter than molecular oxygen (CO versus O2), but it is insignificant in the distribution of gases in an air mixture. (Nitrogen is also lighter than oxygen but they mix fairly evenly in the air.) The general rule is surely to not produce carbon monoxide in an enclosed space.

I was driving out a main drag to Choshi and some clown blasted off a shotgun right next to me off the side of the road...nutcase.

Several years ago a friend of mine, who was the step-daughter of the famous Johnny Cash, died from carbon monoxide inhalation. I hope that Rosie Nix is resting in peace and I wish the same for these gentlemen. Death is an indiscriminate visitor.

Very sad. Rest in peace. Let's watch out for fire especially in a place with poor ventilation.
