Amanda Knox: CCTV Casts Doubt Over Alibi

CCTV footage has emerged that could challenge Amanda Knox's alibi on the night Meredith Kercher was murdered.

A video obtained by Italian television shows a person resembling Knox walking through a car park away from the house the pair shared in Perugia.

The American, who this year was re-convicted of murder after a second trial, has always said she was with then-boyfriend Raffaele Sollecito on the night of the killing.

TV programme Quarto Grado claims the figure shown on the film has similar clothes to those worn by Knox in the days after the murder, and even compares the walk of the two people.

It claims British student Meredith Kercher is also seen on the film two minutes before, apparently heading back to the house.

The route through the car park is said to be a shortcut between the property and the centre of Perugia.

Quarto Grado also says that Rudy Guede, the only person jailed for the murder, was recorded by the same video camera earlier in the evening.

The CCTV is stamped 20:53 on the night of the killing, November 1, 2007, but the Italian television programme says the time could be out by 10 minutes either way.

An author who wrote a book on the case, Barbie Latza Nadeau, told The Times the video was known about but neither side chose to use it in court.

"It's not helpful to the prosecution or the defence. If the prosecution shows someone like Amanda Knox walking away from the crime scene it's not helpful.

"For the defence, if there is a video of her anywhere near the house it's not helpful to them because her alibi is that she was at Raffaele's house," said Ms Latza Nadeau.

Ms Kercher, from Coulsdon, Surrey, was found dead in her apartment on November 2, 2007. Her throat had been slashed and she had been sexually assaulted.

Knox and Sollecito were arrested four days later and served four years in prison before they were acquitted by an appeals court in 2011.

The high court in Italy overturned that acquittal and ordered a new trial, and in January Knox was sentenced to 28 and a half years and Sollecito 25 years.

The judge said Knox acted with Sollecito and Guede, but it was she who delivered the fatal knife blow.

Alessandro Nencini said Knox was motivated by a "desire to humiliate" Meredith Kercher after she accused the American of taking money from her room

Knox, who lives in Seattle, is appealing to Italy's highest court and last week told CNN she "never fought" with her housemate and the pair were "becoming friends".

"I did not kill my friend," she told CNN. "I did not wield a knife. I had no reason to.

"There is no trace of us. If Rudy Guede committed this crime, which he did, we know that because his DNA is there around Meredith's body - his handprints and footprints in her blood.

"None of that exists for me. If I were there, I would have traces of Meredith's broken body on me. And I would have left traces of myself around Meredith's corpse."
