The ability of human beings to inflict pain and misery on each other can never be overstated. All we have to do is look at what is happening in Darfur to see that. Still, every now and then there is a story which literally takes one's breath away. Such is the case with the murder of two French students in London: http://www.telegraph.co.uk/global/main.jhtml?xml=/global/2008/07/03/noindex/nfrenchstudents.xml&CMP=EMC-expat2008. The victims were seemingly chosen at random, and were tortured before dying and then mutilated after they were already dead.
What kind of a sick mind does something like this?
UPDATE (7/4/08, 10:58 a.m.): Police are now investigating whether an earlier burglary in the same flat can provide any clues into this horrific murder: http://www.telegraph.co.uk/global/main.jhtml?xml=/global/2008/07/04/noindex/nstudents.xml&CMP=EMC-expat2008.
