(ANSA) - Rome, November 20 - A US student
accused of the murder of British exchange student Meredith
Kercher, hated her ''snobby'' roommate and meant to punish her,
prosecutors said Friday while delivering their final arguments.
Amanda Knox, 22, is on trial together with her former
Italian boyfriend, Raffaele Sollecito, 26, for stabbing Kercher
while forcing her to participate in what prosecutors described
as a ''perverse sex game'' in November 2007.
The two then allegedly broke a window in an attempt to
simulate a break in.
