Reading the news story, my speculation is this was a gang hit.
Most likely a hit by Salvatrucha MS13 or a lesser probability of a Mexican Cartel affiliated gang like CJNG.
These sick fucks would consider a Hispanic who might be associated with them in illegal activities and who was a member of the Military of LEO as a traitor deserving of decapitation, a favorite form of ultimate cartel “justice”.
We’ll see how this plays out.
