Yes, but I've never been able to recreate it in many tries with the same cord. It doesn't stay put.

To me what is odd is that perp put a slip knot on "both" ends. Normally a garrote is not done like that.

But if you were to hog tie someone, then a slipknot would make sense. It is possible that he hog tied her first.

Another thing that amazes me is that think a slipknot is so unique and that many people would not know how to make one.

It is one of the easiest knots to learn and is very commonly used in my opinion.

I have to read the report again about the rope to see how long it was and this would play factor in how it would hold once it is twisted. Also using a rope that is wet would help it stay put.
