It’s not backwards...it’s upside down....the “B” that is. This could be significant. The perp could have been holding her down sitting over her head, facing her feet, in which case the “B” would have been upside down. Flip the photo 180 degrees. I’m sure you’ll understand what I’m talking about.
How did he control her hands and feet then?? The more I read, the more I question this story.
If you are right, and I think you are, the perp was right handed.
