Who was the murders of hiram?

Commonly (if the answer you are looking for is relating to the murder of Hiram Abbif) the answer is that there were three men (according to the system of the Free Masons)
the names of the three men are as followed chronologically
Jubilah, Jubilo and Jubilum (apparently they were brothers).


In the Freemason rituals (and in their philosophy)
each murderer is symbolic to the Three Poisonous Enemies that can easily corrupt and destroy a noble society, community, and country.
The three enemies are as followed chronologically
Ignorance, Fanaticism, and Tyranny.

the last murderer (Jubilum) is represented as the last enemy (in the Free Mason Rituals) because since he was the one (accordingly) who gave the final and devastating blow to kill Hiram, he was labeled as the symbol of Tyranny. Because Tyranny is not only the most Destructive, but it is the ultimate source that can share and relate to "both" Ignorance and Fanaticism and to which Tyranny can be the result of.


Even though this source (from the Free Mason) is very detailed, but (apparently) there seems to be no exact Archaeological proof that this account had actually happened.
Even though there's Scriptural proof That Hiram Abbif existed (in second Samuel 5:11 and first Kings 5:1-10) But there was no Scriptural record about the Murder or his Killers.


The reason why he is a valuable person in the Free Masonry was because he was a Builder that help with King Solomon's Temple (accordingly), and he used a philosophy involving Masonry. Which is why he is believed to be the beginning of the Freemasonry.
