There are quite a few firearms that could of been used in this situation, but I am suggesting it could have been the MAC-10 machine pistol. This gun has a high fire rate and is effective at close range, therefore being able to eliminate multiple targets at once with little accuracy needed. Combine this firearm with the optimal accessories and it could of fitted this scenario exactly. The MAC-10 most likely would have been fitted with a two-stage suppressor either designed by Sionics [1] or sound suppressor by Wellbell [2]; it may have also had an empty shell/cartridge collector [3]. The MAC-10 may have also been fitted with a foldable stock and/or strap, both to increase accuracy. The ammunition used in this firearm would have been a 9x19mm Parabellum or .45 ACP depending on what the gun was chambered for, both are typical pistol or machine pistol ammunition.

Closer inspection of the bullets either in the people or walls would of given a better idea to which cartridge was used. The loud altercation was most probably an argument between the 4 people involved, the 3 dead and one man leaving the scene. The bullets did not perforate any of the victim’s bodies; this means the bullets were most likely unjacketed or semi-jacketed; both make a large permanent cavity, although the semi jacketed makes a larger temporary cavity than the unjacketed [7]. Both types of bullet have high impact deformation, although unjacketed does deform slightly more than unjacketed. If the bullets used were unjacketed, they would of most likely would of “mushroomed” and been stripped to the core on impact. The semi-jacketed bullets are also more accurate than unjacketed [7]. Police use Jacketed Hollow Points (JHPs) to reduce collateral damage [8]; the shooter may have been able to get hold of some of
