Can anyone link me to the proofs of dead voters and the like?

They were all over here and now I can't seem to find them. I have a friend who doesn't believe it and keeps referring to his Google searches as lack of proof to support it. He's also saying benfords law isn't relevant to voting.... I can't seem to find the sources that I previously saw showing it has been used to determine fraud occurred in voting.

Bonus of you can help me find the will smith's grandfather voting and frazier as well.

I tried searching, it's not coming up for me.

Thanks in advance
