Amanda Knox, the American woman accused of murdering Meredith Kercher in Perugia, Italy, hid her face from images of the murder scene in court.

Knox, 21 and her ex-boyfriend Raffaelle Sollecito, 24, are accused of murdering the Coulsdon student in a sex game that went wrong in November 2007.

Last week the court saw images of the blood-spattered room with Miss Kercher’s face and foot sticking out of a duvet and a bloody handprint on the wall.

Minutes before the scene was aired, Sollecito and Knox had been exchanging smiles and whispers.

Knox covered her face as the video showed Miss Kercher’s face, but Sollecito watched the whole video.

Earlier, Italian police had strenuously denied the murder scene had been contaminated and said they matched the hand print to drifter Rudy Guede from Ivory Coast, who was found guilty of Miss Kercher’s murder in a fast-track trial and sentenced to 30 years in jail.

Amanda Knox’s father sat behind her making notes as the footage was shown.

He later said his daughter is anxious to testify and prove her innocence in an interview with NBC.

The trial continues.
