Just wanted to tell that I seem too have two Louis Letrush NPC near stables near Whiterun after porting my self there.

Yeahthis is from the vanilla game not caused by dawnguard

Try killing them

^^ This. It's a common bug. I have seven of them myself.

I have a few as well, one is merely a head that looks up at me from the ground

All clones are marked as essential. THEY WILL NEVER DIE!!!

They're killable. If there's one "submerged," that's the real one.

Really? All I've ever been able to do is get him to kneel.

I never had it before adding dawnguard

Same here, I had around 10 before I killed all of them.

I think Patch 1.6 changed this because prior to that I couldn't kill any of them, now I have killed them all.

Just 2? You're pretty lucky. This quest has been bugged since day 1, and I have avoided Letrush in the Riften Inn like the plague because of it.

Even post Dawnguard I'm still not able to kill him.

I did it once, never again will that quest be completed...

Have them line up like bowling pins and fus ro dah lol.

I think that you have to witness the random event of a hired thug killing him before he looses his essential status.

My only character to have the battle of the clones eventually killed hers, and it was before the 1.6 patch. It seems once you see Lutrush killed in the wilds by the thug, he is no longer an essential NPC.

it only seems to happen if u do his lil step n fetch in riften...and the only way i got it cleaned up was much later in my game...had 15 of the bastard...is a radiant DB quest to kill him. have no clue when it shows up though but it does.

Twins? Try having 20-30 of him hanging around the Whiterun Stables haha. He's (they) been there for ages though, long before Dawnguard was even announced.

A funny thing to see is...

I had exactly the same glitch! but i had 2 and another which was halfway through the ground. thats so weird thought my xbox was freaking out.

I think I'm up to 17 or something.

This is at 575 hours plus played, or something, and being level 81.

I saw where they came from, the other day. He runs ALL THE WAY FROM RIFTEN. Then he, the new guy who ran all that way,
is added to the number of his fellows (who are already there, at the whiterun stables.)

I was bored, before dawnguard came out, at level 81. So I SEARCHED AND SEARCHED for the random, where an orc in the wild kills
letrush. Evidently that makes it so you can then kill the clones (that is, seeing the orc kill him in the wild makes the copies of him "non essential." )

I never saw that random come up though, in various locations. I tried a fun thing, at possible locations I've heard people mentioned. I saved in several places, until my save was just before a "random encounter." Then, upon reloading that save and running a bit to that location again, it might be a
different random.

Like I'd reload and get

Meeq whatever the liar

then maybe some imperials with a prisoner,

then maybe some thalmor dudes, etc.

but I never managed to get a "letrush with an orc" one.
