What proof do you have. I am happy to be corrected with a source. Its assumed they knew, by people in the internet who know nothing. We literally know nothing. If I came home in a van and my family was under the impression I financed it or co owned it and police came and confiscated it and the father of my Ex came to the house and there was an altercation and LE had to be called for whatever reason. They would probably hire a lawyer for me as well. Would they think I murdered someone, No. But they would at least think "oh crap, theres going to be a car theft charge." We don't know what he told them. He seems to be pretty convincing when needed.
Brought this over from the previous thread because I wanted to say that I would certainly know whether or not my son was an owner, or co-owner of a vehicle that he was going to be traveling/sleeping in all over the country. If BL said it, which I doubt, his parents would simply say “we know how much he worked, and there is no way he had the money, and no bank would finance it, especially with no job.” No way did his parents think he owned that van, and no way did they not not wonder what happened to Gabby when he came home without her. And if they did not know what happened to her, or strongly suspect, there is no way they would have ghosted her parents. No. Way.
