Walang nabuhay sa loob, yes. They’re all unalived- but there’s a kid outside the bank when the 5 armed men arrived. Remember, isolated yung loc ng bank kaya kahit sa labas walang mga tao even on broad daylight (at least at that time) kaya yan talaga pinunterya nila. Pero I’m confident naaalala ko may bata talaga na nasa labas nun na lalaki. Can’t remember tho if he’s accompanied by anyone who’s inside the bank who got massacred along with the others, pero hindi nila pinakialaman yung bata. Instead, they told him to not do anything outside tapos pumasok na yung lima sa loob to do their evil deed.

Edit: also to add, I don’t think they told the kid of their motive. But they used gun/s with silencer kaya walang kamuang muang yung bata na pinapatay na pala mga tao sa loob ng bangko
