And for all those saying there's no DNA, I'm pretty sure there was. Here are some points I pinched from another site:
- Knox’s DNA was found on the handle (Kercher’s DNA on the blade) of the knife used to slit Meredith’s throat.
- An abundant amount of Sollecito’s DNA was found on the clasp of Kercher’s bra, which had been forcibly removed (the bra was severed with a knife). Knox’s DNA was also found on Meredith’s bra.
- Luminol, a chemical agent used by forensic investigators to detect blood at crime scenes, revealed bloody footprints all over the house. The footprints were compatible with those of Knox and Sollecito. An additional footprint, believed to be Knox's, was found underneath Kercher’s body.
- There were no less than five separate instances of Knox’s DNA being mixed with Kercher’s blood in three different locations in the house they shared.
- The morning after the murder, Knox showered in a bathroom with Kercher’s blood still smeared across the sink and floor.
- A shopkeeper testified to seeing Knox come into the store to buy cleaning supplies, most notably the bleach that was used (unsuccessfully) to clean the murder weapon, at 7:45 on the morning after the murder. Knox claimed not to have gone to the store.
- A staged break-in designed to throw off the investigation was quickly dismissed by police because the window had been broken AFTER the room had been ransacked. Nothing had been taken in the “burglary” btw.
- Knox and Sollecito gave multiple and conflicting accounts of their whereabouts on the night of the murder. None of their alibis was credible.
- On the day after the murder, Knox phoned Kercher’s two cell phones, to help establish her false alibi that she was at Sollecito’s apartment. She was then seen throwing the cell phones into a neighbor’s backyard, presumably to aid the burglary story.
- Knox was photographed kissing and cooing with Sollecito as the forensics team was removing her roommate's blood-soaked body from the house.
- Knox was seen turning cartwheels and doing handstands after being interrogated at the police station. She evidently thought she’d (literally) gotten away with murder.
- Knox falsely accused Patrick Lumumba, a former employer, of murdering Kercher. She admitted she knew he was innocent in a conversation with her mother which was intercepted by police. She later changed her story to implicate Guede as the murderer.
- Knox voluntarily admitted that she was involved in Kercher’s murder in a handwritten note she gave the police, one week after the crime.
- Knox was constantly laughing, smiling and “voguing” for court cameras during the murder trial.
- Knox was known to be promiscuous, very kinky in her sexual appetites and heavily involved in drug use (mostly methamphetamine and hashish). Evidence suggests Knox disliked Kercher intensely and was jealous of her good looks in particular. They’d only occupied the house together for a week and were not friends.
