There was pretty convincing physical evidence implicating Guede, according to wiki.
"On 16 November the Rome forensic police matched fingerprints found in Kercher's bedroom to Rudy Guede,[129] a man originally from the Ivory Coast who had lived in or near Perugia since arriving in Italy with his father when he was five years old. Because he was an immigrant, his fingerprints were on file, and on 20 November he was arrested in Germany, where he had fled days after the murder. His DNA was later found at the crime scene, on and inside Kercher's body.[130]
