> “After the execution of court-authorized search warrants of online accounts controlled by Lichtenstein and Morgan, special agents obtained access to files within an online account controlled by Lichtenstein,” the press release said. “Those files contained the private keys required to access the digital wallet that directly received the funds stolen from Bitfinex, and allowed special agents to lawfully seize and recover more than 94,000 bitcoin that had been stolen from Bitfinex. The recovered bitcoin was valued at over $3.6 billion at the time of seizure.”

So most likely,

1) they didn't launder it properly, leading to police being able to trace it to their bank accounts. I wonder if tornado.cash was used.

2) then police had their names, leading to warrants for all online accounts - google account, apple account, etc.

3) they made the big blunder of keeping their private keys in their online account. Most likely a txt file in google drive. That is such a silly blunder. Without the private keys, the police has zero proof of anything. They could have made a hundred excuses for how they got money in their bank account, as long as the police didn't have the private keys. Who keeps their private keys in an online account?

Apparently the biggest criminals make too many silly mistakes. The old saying applies here: "you don't have to be smart, just don't be an idiot"

Well, the police had a search warrant, so the police could have found them if they had had them in their possession anyway.

Sure, they could have destroyed them, losing the money but maybe not getting arrested?

vitalik (ethereum founder) used an interesting system. He split the key in 2. Wrote both on paper. Gave 1 paper to family and kept the other. Even if the police raid him (hypothetically), they cannot raid the houses of his family and friends at the same time

This way the police or anybody else cannot get your private key.

or you end up with a useless half key or your trusted accomplice helps in the investigation

The police don't know that you split the key. But I get what you mean. I am sure there are better ways to hide private keys.

Encrypting it with a good password that you remember and then printing the encrypted keys comes to mind.
