It has always amazed me that people has accepted MP's statements about that night and what went on in Brewer's house as "the facts" in the case. We actually have no reliable witnesses. Not Brewer. Not GC who told Nancy Grace he did not let SG in and then changed his story to an elaborate one about letting her in and not MP who said he saw her under the boat and then poof she disappeared into thin air and so basically did he. And then we have no explanation for "the drifter" whatsoever. I would say we absolutely know nothing about that night for sure.
I wasn't saying I believed what MP said. I was just referring to theory that GC was setting MP up and SG was already dead.
