Thank you for taking your time to make this report
Given the information provided, it seems you are in the wrong here.
You should clarify in future with the detective if he has the DNA, your claim to playing with sound off seems to not be true as Kurze informs me that you also heard people shooting in the round before, as well as your speakers on mute does not remove the heads up display of who is talking, and you knew Kurze was the one beside the C4.
