Absolutely this. Very very likely the pass is some total bullshit and with it you can just open with keepass normally. Talk to your friend and list some of the dad's basic info, like names of close people, relevant dates, pets, hobbies, etc and just try those and combinations of those.
I barely ever talk to my sister and once she left her laptop with me so I could fix it and forgot to leave me the password for logging into it. Believe it or not, without knowing that much about her life, I nailed her password in literally the first guess and got in. People are that retarded.
If that's not the case here, you can also try to look around his stuff for programs that can generate either crypto or random strings intalled in his machine. Then you might be able to find out what type of more complex pass he's used and maybe try those programs comboed with the first suggestion.
Do post results later. Not necessarily his personal info, but just if you managed to get in or not, and if successful how.
