The beginning of modern day Jack the Ripper(s)?

Upon getting on a train for what was to be a fun day trip to Bath, maybe listen to my iPod for a little bit on the one hour trip, I could not help but pick up one of the numerous copies of The Metro lying on and around the seats of the train.  What grabbed me was the headline reading, " 'My Lolo's murder will be avenged.' " As Hannah, sitting next to me, picked up a copy, we could not believe what we were reading.  Two French men, both 23 year old students, were murdered in Scotland Yard (Southeast part of London) on Sunday. But this was no ordinary murder.  The men had been stabbed over 200 times after having been tied up, gagged, and tortured.  80 of those stabs occurred after the two were already dead.

Following the murders, the men/apartment were set on fire.  What was even more disturbing was the fact that the London police had yet to see a murder this brutal in London.  The comment that really intrigued me, and is related to the Natural Born Killers murders, was the fact that the murder was either a demonstration killing or psychological, as if the killer(s) had watched Quentin Tarantino films over and over again.  It is very disturbing to think that people, just like the Natural Born Killers, could take "inspiration" and ideas from movies and actually mimic them in real life.  Although these killings are so rare, it is horrifying to learn about something so gruesome that has happened in the real world.  I cannot even imagine the impact it must have on the people closest to the victims, because it has such a profound impact already on the general public.  The headline of the newspaper was a quote from the fiancee of one of the victims and how she will not rest until "Lolo's" death is avenged.  

The killer(s) are still on the loose, and although the police have some vague idea of a man who could have potentially committed this crime, they are still very sure.  In this day and age, we are so used to the police having suspects and catching the criminal(s) within a couple of days of the crime.  So just like Jack the Ripper, this man/these men have no identity, and have so far gotten away with a horrifyingly brutal crime.  Will the killer(s) be caught? And if/when caught, what triggered the fascination and determination to commit such a heinous crime? How much of a role did the media actually play?
