I think you might be right from the posts I’ve since seen.
It is pretty amazing when you read about how profilers look for certain behaviors common to those who commit murders...both before and after the crimes. In this case it was a brutal murder and rape of the victim...lots of blood and messy.
Guede hung around for a time before fleeing, whcih is why he covered the body up...he couldn’t look at the gruesome sight. During his trial he repeatededly said there was “just so much blood everywhere”...which of course was still bothering him even then.
Also the knife they tried to claim had Knox’s DNA on it was not the weapon...it didn’t fit the knife wounds even close. It was not the weapon used. An dinteresting that Guede was known to carry knifes.
So who is likely to be the stone killer? This squemish boy, or the girl who suposedly came home to an unlocked apartment, noted blood all over the floors, and decided to take a shower before doing anything else?
