DNA does not change over time. Some diseases (the big C) will damage samples of DNA taken from affected parts of the body (and even then, not by much).
If a person's DNA changes over time, how can it be reliably used to identify a missing person or criminal after years or even decades have passed?

I don't know where you got DNA changes, but it doesn't. Even transexual people who go through surgery and take hormones to appear to be of the opposite sex they were born still have the DNA that says they were their original sex.
DNA can't change over time that much .it does change but it keeps the main data that it can be identified who we are
It doesn’t change.
I read this question and I thought, I was not aware that DNA
can change. So I looked it up and from what I have understood, despite the fact
that mutation occurs in some cases, it does not change so much that it will be useless
in identifying a missing person.
