Mother died with no will; question about her car

My mother passed away with no will. I have possession of her car and possession of the title (still in her name). No spouse. I understand that her children would split her estate evenly. The issue is, my sibling has cut himself off from the family and I cannot find him. The car needs to be scrapped soon, as it is on my property and is an eyesore. I'm not sure what to do.
