A hard drive isn't evidence
It's referred to as an exhibit, but it's more a scene of crime.

If the investigator has found absolutely nothing other than an encrypted container file, then they can either get the password, crack it, or give up. They would have had intel of some sort to get a warrant to seize the computer, so finding absolutely nothing other than this file would call the validity of that intel into question.

Obviously I don't know what the Investigator has found, for all we know the hard drive could be riddled with tons of 'clues' (without boring you with technical stuff) all pointing to this file.

Do you get the police officers to look under the keyboards for post-its with the password on?

If they're clever they do this anyway.
Sometimes we get them sent with the computers.
Also most of the time the cops ask them in interview if there are any passwords, and let us know if there are.

In assisting you? Probably not very
I can't code or remote hack.
I would be better use as a consultant of sorts.
