The jury in the trial of two students accused of killing Briton Meredith Kercher in Italy has been sent out to consider its verdict.
American Amanda Knox, 22, and her Italian ex-lover Raffaele Sollecito, 25, deny murder and sexual violence.
Miss Kercher, 21, a Leeds University exchange student from Coulsdon, south London, was found with her throat slit in her Perugia room in November 2007.
A 3D computer animation was constructed to simulate the house where the murder took place.
Duncan Kennedy describes the scene.
