Getting Heat from LAPD Investigators

I got a call today from some investigators at the LAPD who said they wanted to "ask me a few questions" about my disappearance 20 years ago.

I told them about the statute of limitations (7 years) on faking ones death, but they persisted and said they have "other ways of getting to me."

Should I be worried?

This may mean I'll have to go back into hiding sooner than I had thought.
