Wish we knew...but search warrant is sealed.
That's an intriguing point. In order to get a search warrant the police must provide probably cause to a judge. I would think that the only reason to seal a warrant would be if the probable cause exposed an innocent party in some way. Lori's warrant was not sealed. And even though it is sealed from the public, I don't think it can be sealed from the target (Chad). Perhaps one of the lawyers here can comment.
I'm not sure I believe Lori turned on Chad. But if she did or suspects he did, we could see an avalanche of new information coming out very quickly.
The reason I don't think she turned on him is because, since she is represented by counsel, the police should not be talking to her without cousel present. And since MM represents Chad as well, he would not allow her to talk. I'm sure there are legal ways around that but I doubt and prosecutor would risk the biggest case of their career by doing something like talking to Lori ex parte.
