"Now the situation is lining up." Realizing that he was observing the scene of that famous criminal case, Leonard Ethan immediately perked up, as the next part would likely reveal the core of this mystery.
It must be said that Mr. Garcia's bodyguard was somewhat amateurish, as normally in such an attack, the first thing a bodyguard should do is accelerate away from the dangerous location, not get out of the car to check the situation.
