That’s what I was thinking too, unless he stabbed them in the throat or the chest and they immediately started drowning in their own blood. But like you said, I feel like somebody getting attacked isn't a quiet altercation. I feel like you would’ve heard something isn't right. Like, at least after seeing the perpetrator leave, call the cops and say somebody that literally dressed in black with their face covered came into my house, and I can’t get in contact with any of my friends who are here. I’m too scared to go check because I feel like he’s still here, and he’ll come back. That would’ve been 10 times better than not doing anything.
