Kim, I don't remember if Robert's was on Dateline or not. I was at the computer and only halfway caught the program. I asked my husband if he remembered seeing it and he said he did.
I just got back from taking my 90 year old father to get some physical therapy for his back and it looks like I have missed some good stuff. In the process of catching up now.
I hope your dad will be ok.. It appears this witness was unaware that DW (or his son) may have had a dark side. I wonder if she knew what the mom and sis thought of him..
