It was four years ago today that Italian police broke down a locked door inside a house in Perugia, Italy. There, they discovered the lifeless body of Meredith Kercher. Her throat was slit and the 21-year-old British student was lying on her bedroom floor in a pool of blood.
A few weeks later, police arrested Rudy Guede for the brutal murder. Police had found Guede's bloody fingerprints at the Kercher crime scene.
Within a year, Guede was tried, convicted and sentenced to 30 years in prison (later reduced to 16 years on appeal). That should have been that. But, of course, the case didn't end - or begin - with Guede.
By the time Rudy Guede was arrested in mid-November 2007, the Perugia authorities had made a profound error - they'd jumped the shark.
