Nice poem. That is how I feel a lot. Do you need me to answer something?
I would say the X set of foot prints are ernies because the mop suggests he was mopping the floor and ran away threw the water when the shooter came it, but i also think the killer was Check C because they appear to be left handed and if they leaned against the wall with their right hand they would have shot with their left hand which would make that their dominate hand
