According to the owner, he's pretty sure it's a BCM BCG. He's had it a long time and a lot of rounds. He's going to clean it and see if there is a laser etched ID on the outside.
No word if it has made contact with the lower yet.

Here are my initial thoughts:
As others mentioned, the front screw looked liked it failed primarily due to over tightening.
I'm not sure why the second screw failed. But close up pictures of the cleaned second screw (the broken areas) could be very informative.
I could be wrong, but I don't think this is a BCM bolt carrier. The gas screws in the picture look different from the BCM screws I have seen. The BCM screws are flat top with a sharp outer edge, not slightly rounded like in the picture. The screws in the picture may be fine quality, but they are different than BCM's.
I'm curious if the shooter had any short stroking issues, when shooting unsuppressed, before this failure.

If it is old enough it might not be marked if my memory serves me. So it could be a BCM BCG that was built before they started marking them. Depending when he bought it. I would say 2012 or there abouts it damn well better be marked.
ETA:
I would rely on IG to know the details of the screws. If he says it ain't I'd bet money it ain't. Only thing I could think of then, is might be a BCM Bolt in an different carrier. I did see that shit back during the SH panic, among other things.
