I was in the situation and I can confirm that Thor was in the game a long time after the sit, Martinez had plenty of time to dispute him but decided not, that's his first wrong.
In the 2nd video you can hear Martinez targeting Thor at multiple times for example at 2 seconds of the first video ''I'm going to try to kill Thor just so ........'' and at 1.43 in the 1st video you can hear him going ''Oh he's going to be so toxic...''
I feel like Martinez is making this report out of his anger against Thor and it feels like this is targeted (witchhunting).
Also adding that executing your teammate is allowed, He was blocking me therefor I had to execute him. If you've got a problem with the execution feel free to bring it to HC.
