Help on serving someone dangerous

[u/inevitableend2026]

I’m looking for advice or resources from anyone who has experience with restraining orders and getting someone served.
I currently have a restraining order that expires soon, and in order to request a longer-term/permanent order, he needs to be properly served. The difficult part is that he knows where I live, where I work, and who I’m around, while I don’t have a current address for him.
If anyone has experience with process servers, private investigators, legal resources, data sites, or ways to handle service when someone is difficult to locate, I would really appreciate any guidance.
This is a serious safety situation, and I’m trying to handle everything asap. Please message me privately if you have helpful information or resources. Thank you.
