Given his prominence, as well as DoJ's priding itself to have solved the two murders in such a short time, one would never expect that it doesn't know the real name of its prey. Getting Bantag's full name should have been a breeze or as the clichè goes, "a walk in the park". All it must do is look at the personal file of Bantag in the Bureau of Corrections, which is under its jurisdiction. Or it could have gotten from the Philippine Statistics Authority. And if it is too lazy to do either of that, it can just google Bantag's name, and his full name will pop out.
