If you have not been charged with those crimes, then the answer is likely, "No." If you HAVE been charged, the answer is probably, "Yes."
It's kind of hard to make sense of what is going on because all three of your posts are rather disjointed. If I have this straight, you allegedly committed these serious offenses many years ago but were never charged ... now, you are contacted by a cop who you believe is your ex's new boyfriend ... you have also been served papers asking the court to revisit the custody issue.
Okay.
Now, how is custody paperwork going to cost you a security clearance??
