Brief summary of what happened:
In the wee am hours of 7/13, Panzaera was ranting on about  some big grief, and from what I could tell via chat, Panzaera was instigating things.   I decided to check them out on the map and saw there were four of them all clustered together at the grief location.  I wasn’t too far from my village so I ran over there.   When I arrived at the scene, the grief was obvious and blatantly deliberate.  There was even a chest for "griefing materials".   
Panzaera and someone else who’s name I can’t remember had dug a shaft straight down and were mining below.   I know this because I went after them and killed Panzaera, who had 4 diamonds in her inventory.  Their digging seemed very targeted and they also made a few comments about using x-ray and free cam.  But I can’t know for sure if that’s what they did or not.  Very suspicious though.
At the grief site, I broke some blocks digging down to where they were mining and also on my way back up.  I also placed a column of cobble to get out of the big pit they dug in front of the gate.
