The kid that jumped off that building did not have a fucking gun

[Irish_Dem]

13. There are only a few explanations.

The gun could have been hidden at the location ahead of time.
That is why we don't see him carrying a gun up the stairs?
Or when he is jumping off the building.

Or he took the gun apart and the gun was hidden on his person or in a backpack.

Or there was another person who helped him.

Or perhaps he threw the gun off the building before he jumped.
