Closer to the base of the neck, with the front of the ligature being below the Adams apple. The point being it was not up under the jawline where most stranglings occur.
I believe, until I hear differently, that it was a slip knot. I'm in the minority, I realize and will certainly concur if I have different info in the *next* 7 years or so.
The autopsy photos don't include a shot with the garrot still intact, so all I can do is go by what a typical garrot is and how it's applied. Plus the depth of the rope in her neck, which is amazing. Again, we're talking about a tender six-year-old neck, not an older child or adult.
You're not looking at the same photos I am, evidently.
