Me and Mike's house griefed, proceeded to kill us

Me and EradicaterMN's house was griefed; He claims it was andrea3640. It'd be confirmed if we had the skin. They smashed our glass, killed both of us (I lost around ten levels which i was saving for enchantments), then he/she ravaged our farms and apparently harvested our floor, and the glowstone which took quite a while to get. One of our new chests were also stolen from apparently (new, haven't protected it yet), so we lost our nether brick according to Eradicater. Also, i lost four brewing stands after he broke into my home to kill us, and the blaze rods costed a fortune.

We left the area untouched and not rebuilt as evidence.

Can you provide us with Coordinates of your establishment?
