Is campos dead or alive?

Alive, and his house is being guarded 24/7 by LEO. Meanwhile Paddock's house was left unattended and someone broke into it. Active mass murder investigation and they didn't even secure paddock's house? Unreal.

So then we can logically assume campos is a threat and possibly a shooter?

It was a perfectly executed hit on somebody at the show or in the area. Hitman steals Paddocks guns from his house and plants them in his suite. Kills Paddock and makes it look like a suicide. Then busts the windows out and uses the long range setup rifle to make the shot on his target. Once he makes the shot he opens fire with the slidefires on the rest of the crowd to cover up his hit and make it look like a lunatic went nuts. Rolls out before anybody gets there.

I watched Jack Reacher too

But you ignore the evidence of two shooters.

This thread needs to be split into a "confirmed facts" thread and a "conspiracy theory" thread a la the walking dead tv vs. comics threads on the movie/tv board

Agreed. Need someone to set up a conspiracy theory thread for the nut jobs.

Based on an audio analysis done on a video taken during the shooting from a specific area in the concert and applying the ballistics of the reported round used, it shows that shots came from two different distances. That distance was a difference of over 200 yards according to the analysis of the sound waves.

I've already done the math that disproves that very poorly assumed hypothesis. I'll put my two posts on the subject into a single reply.

I won't call myself an expert but I am a firearm enthusiast with a solid background on firearms acoustics and professionally part of my job deals with acoustics, acoustics attenuation, and acoustic testing to industry standards. I do this math every day and because I deal with noise attenuation I am familiar with how sound travels and is generated.

Guy gets much of the math right but your math is only as good as your assumptions and his has glaring weaknesses. His math does not take into account the distance the recording device is from the sound of the "ricochet" (which is the supersonic shock wave not a sound of a ricochet but that's another argument). His math only works if the bullet is fired directly at the recording device. The sound from the "ricochet" also has to follow the laws of physics. The farther away the bullet path is from the recording device the longer time it will take for the sound of the "ricochet" to arrive at the recording device. He doesn't know that relationship so he can't accurately calculate the distance the shooter is away from the recording device. That's a pretty large venue the recording device could easily be 100+ meters away from the bullet path and therefore the source of the "ricochet" sound. Because of that delay the farther the round is shot away from the recording device his math would calculate the shooter as being closer than he actually is. Without knowing the exact location the recording was made and exactly how far the bullet noise was generated away from the recording device you can not mathematically calculate the distance from the shooter with any type of certainty.

TL-DR: That guys math is all wrong.

Lets not guess lets do some math. Using Google Earth pro I measured the front of the stage at 330m away from the corner of Mandalay Bay.

A position 84m away from the stage would be towards the rear of the crowd. That is 370m away from the shooter's position. Gunfire report would travel from the shooter's position to the position at the rear of the crowd in 1.0787s

Flight time to the position at the rear of the crowd I calculate using Strelok Plus ballistic calculator using standard XM193 ball ammo shot from a 16" barrel would be .51s

Flight time for the bullet to arrive at the front of the stage would be .44s

Time for sound to travel from the front of the stage to the rear of the crowd is .245s (84m / 343m/s)

Total time for the "Ricochet" sound to arrive to a listening position 84m away from the stage is 0.44s + .245s = .685s

Audio delay from the "ricochet" to the report of the rifle at a listening position at the rear of the crowd if the shot was fired directly at the listening position assuming zero delay from the "ricochet" sound would be 1.0787s - .51s = .5687s

Audio delay to a listening position at the rear of the crowd if the shot was fired towards the front of the stage would be 1.0787s - 0.685s = .3937s

That is a difference is .175s less audio delay.

0.51s - .175s = 0.335s is the new calculated flight time using the bad assumtion.

Again using Strelok Plus ballistic calculator a flight time of .335s puts the shooter at a position of 260 meters away from the listening position.

I said the video poker winnings were bullshite all along. You don't win at video poker the longer you play. Its a computer program designed for the house to win. I could believe a good poker player could win big and consistently playing against other humans, but not video poker. That's bullshite.

Interesting. Good work. Not sure I followed it all but at the beginning you said you thought corner was 330m away but then at end your calcs show only 260m away?

Is that a poor interpretation?
