Do you mean the Peterson family member that accosted Dan Abrams during a break regarding Amber?? That was bizzaro but then everything the Peterson clan does is.
Lisa Bloom was the person that did a little rant on Dan Abrams show about Scott continuing to see Amber after Laci disappeared. Later in the show Dan said someone had called in to correct a statement made by one of his guests (he didn't know which guest made the incorrect statement). I didn't see the show, read the transcript posted here on FR.
