Ο δολοφόνος φέρεται να έκλεισε το στόμα της κοπέλας, με κομμάτια από ύφασμα, πιέζοντας τα αφόρητα και σφίγγοντάς τα προς τα μέσα με την παλάμη των χεριών του. Μάλιστα ο στυγερός εγκληματίας φέρεται να έφραξε και την μύτη της.
The murderer is reported/alleged (to have) closed the girl's mouth, with pieces of cloth, pressing them unbearably/intolerably and squeezing them inwards with the palm of his hands. The hardened criminal even reportedly/allegedly blocked/covered her nose.

The paragraph right before this talks about the medical examiner's findings of suffocation. However, this excerpt qualifies its reporting twice. One in each sentence, which says "reported/alleged." Reported/alleged by whom? The medical examiner? Or is this a mash-up of media reports of what B or LE supposedly said?
And even if this report is accurate it's still consistent IMO with being suffocated while face down (e.g. suppose the murderer had one hand on the back of C's head pressing her into the pillow, and the other hand on the other side of the pillow pressing upwards).
So I'm still going with my face down theory, and the possibility that a pillow or something similar was used for two reasons:
1) LE's repeated statements that no DNA was found on her nails, and 2) B's recent statement, as reported in the media, that C was turned around and face down towards the pillow or sheet (I posted the translation of this a few days ago)
