I already discard that theory, the TX was publicly broadcasted according to mempool.space data. The TX was match with the expected block.
According to
blockchain Broadcasted on 10 Sep 2023 5:02:56
And the block was mined:
Mined on September 10, 2023 5:10:01
Almost 7 minutes on mempool, that actually can be mined by anyone with some decent hash rate or some luck.
So if you want to launder you shouldn't use that way.
