BTC successfully recovered in the Qian Zhimin case, with clues coming from his computer login password and several mnemonic phrases.

BlockBeats News, on December 3, Caijing Magazine revealed that the main culprit in the 60,000 BTC money laundering case, Qian Zhimin, carried a laptop with a built-in cryptocurrency wallet when fleeing. After several searches by the UK police, multiple mobile phones, computers, and USB drives were seized. One of the USB drives stored photos of pages from Qian Zhimin's notebook, and it is suspected that the relevant pages had been torn out before the police confiscated the notebook. The page photos recorded the boot password for this black laptop and several mnemonic phrases, such as "number + love," along with some hint information about the numbers, which made the previous seizure of bitcoin possible.
