WTF? Hacker? Nope, just a cheater exploiting a bug.
In real time it looked like & felt like we were killed by an invisible player. Even when I went back & watched it again it felt like that. It wasn't until in another match with some other people they made me aware of a glitch/bug people have been using to stay miniaturized for the entire game. So once I went back & without blinking I was able to see this cheater. I slowed it down because in realtime it's real tough to see them.
