My Cousin Is Threatening To Murder My Mother And Grandparents.

This may sound jumbled so bear with me. I also dont know my entire family lore, but heres it in a nutshell. My cousin Erik has always just been a dick. He doesnt have custody of any of his kids, has been in and out of jail my entire life, and just overall shitty. This beef started in like august of last year because he broke into my great grandmothers house when she first got put into assisted living and stole all of her dead husbands stuff to pawn, and burned all of her family memorabilia and family photo albums dating back to the 1970's. After my mom and grandparents figured out it was him, hes been getting worse. He tried to burn down my grandparents house with them inside asleep last night.

My mom and me suspect he has active warrants in Tennessee or Virginia right now, although were not sure what county. Is there a way to find out if he does? My mom asked me to look, and i figured reddit was the best place to ask.
