Sorry for your loss. I’d second the trauma theory. I’ve had horrible luck w them. Bought one and it got a bit squished at lfs during capture. I brought it home and tried my best but it didn’t survive long. Few days. LFS replaced for free. Would you believe it jumped out of the transfer bucket on the way to Dt? I grabbed it off the floor with my bare hands in a panic and dropped it again! Next day,
It had a big red mark on it’s side much like the redness on your guy’s face. Assume it was trauma from all the falls

needless to say, he didn’t make it either. I didn’t have the heart to get another one after that.
