Private key of a specific bitcoin address I need to find out the private key of a specific bitcoin address '1FVoAyGnHueH1uNR4dAQgRZcsBkAd3Mo3K'. This is the bitcoin address of a scammer who made me lose my last savings in the name of cryptocurrency trading. I recovered the fund with the help of a special intelligence unit but it is still 'Non-spendable'. Please help me recover my funds and save my life.
You cannot.  If you could, the cryptography on which Bitcoin relies would be worthless.

I don't know who this "special intelligence unit" is, but if all they did was find the address, then that is no help.  (If the "intelligence unit" took money from you to find out this address, and told you that they had recovered your funds, then you've been scammed again.)

You have not recovered your funds and you are not going to.  Your time will be better spent figuring out how to do without them.  Sorry.
