It's pretty damn obvious it is,  it looks like a church, they are floating and have halos, and it's a candle light vigil, and it should be removed. It's just wrong man, it's sick to represent the dead children as npcs in the game. If this is how you deal with tragedies then fine, but don't put it in the game.
It's morbid and creepy, they don't look peaceful or accurate or normal, they are floating with their arms out with unfitting heads and bodies, with blank stares and halos, with a candle vigil, in a setting resembling a church, as everyone has discribed it as such so far. 
This real life stuff shouldn't be in the game. Please remove it.
