I forgot to report, now his death wishing will get unnoticed

Riot should really let us report someone after leaving post game chat. Last game our Jax wished my friend that his mother die, he die from ebola and that he is going to troll. I muted him at the begiining, so when we won that game I was really happy and closed the game. Now all I can do is hope that someone else reported him. It's really unfair.
