'Murder In Italy' is an unimaginative title for an interesting documentary, the story of a police investigation which took several years to piece together the evidence pointing to the murderer of a teenage girl. But the implicated man has never admitted his crime, and, while convicted on a combination of DNA and circumstantial evidence, he continues to assert his innocence. As this film tells it, there's a fairly strong proof of his guilt, as well as an interesting tale how small scraps of forensic evidence were slowly fitted together to solve the mystery. Indeed, the story is more riveting than most detective dramas. What remains elusive is the motive - and a final explanation of why this terrible thing happened.
