It is a salvage yard. The seat is really not that out of the ordinary. Agreed, but a BURNT seat next to the very pit they found her bones...IS...significant...If LE had allowed a forensic anthropologist in to the crime scene before shovelling TH's remains, we may know if that seat had any significance.
Your theory.... she had no reason to look for BJ, she knew she was meeting SA... how did she know? because he called her and spoke to her. There is no evidence she spoke directly with him that day. She also told Auto Trader she was going to the Avery brothers. He wouldn't be able to leave her for days..why not...cover her with a tarp in a car there were people coming and going constantly... you realize there was more than just him that lived on that property and it was a business, right...Insulting question, yes I'm very aware it was a business and there were other residences on the property As for not consenting to a search.... he did consent to a search on November 3rd when LE came to his home...No, not true...Earl Avery consented to the search of the property he told them he had nothing to hide.
Am also very familiar with the area...my grandmother was born in Two Rivers--the next town over....I was traveling back in forth from Michigan (where my grandparents lived in 2005)....along I-43 on the weekend before she was killed.
