A friendship made in hell.

Wow ! What a wicked pair .

[@johnhenderson131]

It was going to escalate from the moment they started torturing and killing small animals. Just add bed wetting and starting fires and you’ve got two psychopaths in the making.. no one noticed the signs?

How is the double jeopardy law "silly" ? It was only partially abolished anyway, in the event the "new fresh and viable" evidence were to be revealed, they could now re-try someone.

When I hear would be tyrants say stuff like that I thank God I was born in the land where the few Brits who still believed in freedom 250 years ago chose to start an actual free country.

[@ECFRescue]

To the Brits in the comments if y'all know, why are there so many towns that end in "shire?" I watch so many of these crime shows and there are never fewer than 3 new town names each time, it seems. Also for anyone why the hell is the crime always in August? If you watch these often, you know what I mean. It's crazy.

county Shire is a traditional term for an administrative division of land in Great Britain and some other English-speaking countries such as Australia. It is generally synonymous with county

One of my favorite true crime YOuTube channels !!Really enjoy true crime and you guys always post great in-depth detailed documentaries. I’m from Canada and subscribed not too long ago. Keep up the great work. Really love your detailed work👍👌😊♥️🌟

[@Lanwarder]

I agree, I too am Canadian and I appreciate the good work they're doing...... but I have to ask, is it just me, or on this one specific video the narrator kinda sounds like he's narrating an ad for a Dodge Ram or some other pick up truck lol? Maybe it's just in my head, IDK. What do you think?

[@dennissettlemyre917]

I seen another documentary on the McDuffy guy. At the very end of it, the narrator said that the scary thing is he (McDuffy) probably wasn’t alone when he started. It never explained why he thought that though. I wanna say it was “Histories crimes and trials” that used to be on the history channel back when it was good.

LOVE the British accent, just love it. They do speak and pronounce the words in TRUE ENGLISH being where the English language the place where it originated. Americans speak a dialect of the true English. Too bad for them.

[@diggininthecrates91]

There's no such thing as "True English". The English spoken by the British today is completely different from the English they spoke 200 years ago...

5:47: "jumping at people while wearing halloween masks", lololol i've got one on that. 4 teens trying that on me one night in Brockwell park (supposedly shut at night but night people knew where to get in). Double trouble for them: 1) if you try and scare me i attack first as reflex so no room for scare, some childhoods do that, just keep to yourself and you'll be fine; 2) had a big black dog for partner, who really didn't like trouble-makers & gave it most abundantly. The one nearest to me got punched out, had to pour a bottle of water over him to revive him & ensure he was ok, then he got told off bad to make sure he'd remember why he mustn't do it again; also got their addresses from him coz his pockets, duly checked while he was out, had too much dosh in which he lied about so looked like they were starting to mug too. Took him back to his place to make sure he hadn't lied about that. As for the 3 others, i'm still laughing at how loud they cried, how quick they wetted their pants, how fast they ran and went through the fence. Good times... Good lesson too, i kept an eye on them from afar: they straightened up after that and did well with themselves.

With all due respect ma'am, you can't judge a book by it's cover. Please remember that and stay safe.

[@TheSlothmuffins]

It's not about attention, it's about control.

[@NutsNBerries]

Power and control

[@MijoShrek]

They're sadist. It's upsetting because these kinds of people are so sick and twisted that they get off on the act of it. They were both married when they were raping. And the ex of Duffy helped investigators on narrowing him down on their investigation. She said he was tied her up, and said he would only get peaked of interest if she showed refusal and not liking it the more he enjoyed it like it excited him.

[@Nikki_the_G]

That isn't why rapists rape. They do it to have power and control over their victims, and to humiliate and cause them pain. Do you seriously not know this? You think rapists are just horny guys? wtf
