A suspect with his face covered is escorted outside a police station during the investigation into the murder of British exchange student Meredith Kercher in Perugia November 6, 2007. Italian police brought three people in for questioning on Tuesday over the brutal murder of Kercher in the university town of Perugia last week, including the girl's American flatmate. Kercher, 21, was found in her bedroom on Friday -- which was locked from the inside -- hidden under a duvet and semi-naked with a deep cut to the throat. REUTERS/ Daniele La Monaca (ITALY)
