Sorry for not responding sooner. I had some personal problems.

We managed to find the wallet password, we found one flash drive hidden in his apartment taped under the bathtub ( that part used to clean under the sink ).

It indeed had some BTC, close to 2BTC that the parents decided to cash in, they donated some money ( didn't asked how much ) and some went to family. They also wanted to give me few thousand but I declined.

On that drive however was one more wallet but this one is from late 2015. I tried same password, keys and everything but they don't work. This one is also bigger, 150kb so it could be that that one also has something inside.

So unless we find a new flash drive, HDD, SSD or some unknown email that has password and key i doubt we will open that one.

Anyway thanks for all the help and suggestions
