Previously I had suggested to spend the output with an OP_RETURN message. Ethically speaking, that's neither a good option, because some owner's relatives might have access to that money with a signed transaction wherein he has granted them inheritance. Spending the output would invalidate that transaction which is supposed to be broadcasted in the future.
I get ~120 unspent transaction outputs in the range of [0.61040000, 0.61049999] with the following filtered search request:
There might be 120 unspent transaction outputs with value equal to some of that range, but I haven't read he's said it's consisted of just one output. The owner can have funded bunch of times, with a total value of ~0.6104 BTC.
