Somebody likely mistyped something without bothering to check the information on the screen.
The supposed criminal you are supposedly being confused with is just their refusal to admit they made a mistake.
They would rather run you around than accept any responsibility.

I mean if this person committed their criminal act in '86 that was 20 years ago.
It would have been a problem before now for you if it was really true.

Of course, I could say it is your own fault for having the same name as a criminal
