House near spawn seems to be greifed

I was on 2(?) days ago and micheal came on and then saw his house was greifed, commented on it then left. Yesterday I was passing through the spawn and so I stopped by to take a look. All the log walls were destroyed I grabbed some coords and I dont beleive there was much outstanding there. I don't even know if it is allowed to report a griefed that wasn't me. If so the coords are as follows:
X: -13 Y: 65 Z: 37
I believe the block there was a log

Yeah this sounds like it is a really old griefing. I can keep looking into our older log files, but so far I havnt found any hits for that particular location.
