So, I have been playing around with Neo4j lately and was wanting to experiment using a large dataset. The blockchain struck me as the best dataset for performing analysis. I was always intrigued by this address specifically : 1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a which has around 111114.60025818 BTC with nothing spent. From the recent disclosures on Silk Road and about DPR having safely locked up 600000 BTC into an encrypted offline wallet, I was hoping to find some connect between this address and the address he unwittingly leaked out 1LDNLreKJ6GawBHPgB5yfVLBERi8g3SbQS in this post: https://bitcointalk.org/index.php?topic=6460.msg94424#msg94424

Long story short, I think, if my analysis is not wrong, the address 1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a belongs to DPR. He used a tumbler to mix his coins but looks like it wasn't good enough to hide the trail. I just used a shortest path algo to find the path that leads to the final destination. So here is the trail:
