Ejectment on missing Homeowner

[Devon Daniels]

I am planning to file an ejectment on a home I bought at this years tax certificate sale. I have sent a certified letter to the property letting them know I have the tax certificate to the property and it was returned. I left a copy of the notification letter posted to the door. The house looks vacant and possibly abandoned. How should I file the ejectment if you cant find the landowner? Has anyone ever delt with this type of situation?
