Notice that all the inputs came from this address: 15TEAwEMxVS3BK718HhwgJg7nxwyJ2ib9y. I'm pretty sure if you go backwards you can land at DPR's other accounts.

Also, I don't think DPR just spent it (to someone elses address) as the trail has only addresses that were used for mixing... all the intermediate addresses have exactly 2 transactions... 1 receive from previous mixing address and 1 to the next mixing address all the way to its destination 1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a.

The script I wrote followed a path that had addresses with only 2-10 transactions.
So lets break in down:

DPR's known address: 1LDNLreKJ6GawBHPgB5yfVLBERi8g3SbQS
Tumbler's receive address: 1BG9jDV3pA1MsJUnvRyWuA2b7PfGd4MZaw (only 2 transactions)
Tumbler's next mixer address: 12h6TzwPNBvDnppbsqpyXwW4oo5UUKaKSa (only 2 transactions)
Tumbler's next mixer address: 1EG9HJG9aGqzgGujfNQMiNbyqpKnFxafvE (4 transactions but note that the only output is to 1AHki5AbZYiz4fHkGSTVKN3T1Tv5PwZpnh... the remaining transactions are just too small -> this address may have been reused by the tumbler)
Tumbler's next mixer address: 1AHki5AbZYiz4fHkGSTVKN3T1Tv5PwZpnh (only 2 transactions)
Tumbler's final mixer address: 15TEAwEMxVS3BK718HhwgJg7nxwyJ2ib9y (7 transactions -> Note that this has only one output)
Final Destination address: 1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a

There is no other path followed by the tumbler. So possibly the service used by DPR was pretty weak or probably he just manually mixed it himself.

The 1LDNL....... received 11,329.89 BTC, while only 2,000 BTC end up in 1933phf..... Not saying you are wrong but that's not strong enough.

Is there any other known addresses of DPR?

This is because he split the 11K BTC into multiple transactions (one of 5KBTC and the other of 3K and 2K BTC). I'm pretty sure all the dest addresses for those transactions belong to the Tumbler service. The paths taken for each of the above 3 transactions can be different lengthwise. The script I wrote just followed 1 path (which was the shortest) which turned out to be the 2K BTC one (the path taken could have been any of the above transactions).

Unless DPR knew who the receiver was beforehand, it would not be possible for his 2K BTC to end up as the first transaction to 1933phf. The 1933phf address looks like it was used for only storage (probably offline) seeing that there are no coins spent from that address. This way I could conclude that both the sender and the receiver is DPR himself.
