Here is the video that Albatross Necklace posted that staff said needed more commentary.
I think this makes a good case for there being two guns.
Especially this:
This is audio from two different phones, so if there's a difference in travel times between shots due to the shots being at different distances from the two different phones you can see it here, and you can see it in shots 3 and 6.
The rest of the video is also very good and everyone should watch it.
