Yes it was former Detective Jubelin who took BS’s ex brother in law into custody over a decade earlier.Seeing as how these things were not done until GJ was on the case, I don't think it is unreasonable to suspect that it was GJ who decided to even have suspicions about Spedding. And for me, I link that to his prior involvement with Spedding's ex-wife's brother, the horrible child rapist/killer, I think his name is JH. Although the search of Spedding's property was done just before GJ was officially put on the case, I believe I read just recently that he was fully aware of what police were about to publicly do to him, and according to GJ, he had recommended against the public display?
