Murder caught in game chat

Before we start This is NOT some primitive creepypasta with haunted beasts in places, etc. This is actual thing that happens daily. Also note that this creepypasta is REALLY short. Lets begin
I was just minding my business on phantom forces getting that skill i've lost almost 2 years ago. Then i saw some random kid (idk if it was a kid. No hate please) and he started to say that someone is in his house throwing everything on the ground. Everyone thought it was an troll so they started laughing and told him to kys (kill himself) But then something rather creepy happened. He started to scream in chat asking for any tips. Then something weird happened. Random letters appeared from the kid. Let's just say it was something like "býuzjiuzýhujikoztgthzu". Everyone was laughing their ass off saying he is obvious attention seeker. But the fact that creeped me the most. He was in game for around 15 minutes and he didn't talk or move. His game then had to shut down because of time limit. But the heck. It creeps me that internet is bunch of meme kiddies. Don't get it.
