Still upset about this

Not sure what group to put this in. Just a few days ago, an older man shot a 20 year old 3 times (stable condition) and barricaded himself in his house and stabbed his dog to death. I’m upset for the dog and still feel sad. This was over loud music at 8:30-9 pm. I live across the street in my city and the other city is where it happened to far from me.
