DNA on Slain British Coed's Bra Suggests More Suspects in Her Death

DNA traces that do not match any of the three official suspects have been found on the bra of Meredith Kercher, the British student murdered in Perugia last November, suggesting that more people may have taken part in the attack than thought.

Forensic scientists working on the case also said they had revised the time of Kercher's death, previously put at between 10 p.m. and midnight on Nov. 1, to between 9 p.m. and 4 a.m. on Nov. 2.

Traces of the DNA of Raffaele Sollecito and Rudy Hermann Guede, two of the suspects currently being held in prison, have allegedly already been found on Kercher's torn and bloodstained bra.

However, police said that two new traces found did not come from either man; nor did they match the DNA of Amanda Knox, Kercher's American roommate, who is also in prison pending charges.

Police said they were trying to establish the identity of the two new people whose DNA had been found, and were keeping “an open mind” about how the traces got there. Kercher was found semi-naked, with her throat cut, on the morning of Nov. 2, in her bedroom at the whitewashed cottage she shared with Knox and two female Italian students.

Prosecutors have said the post-mortem examination showed signs of sexual violence, suggesting she had been killed in a drug-fueled sex game. However, Il Messaggero, a Rome daily newspaper, reported that the pathologist who carried out the exam believed the sexual violence “may have been simulated since no bruising consistent with a rape” was found on Kercher's body. Investigators said Kercher's attackers had also simulated a break-in by smashing a window.

Il Messaggero reported that the new time of death would appear to undermine the alibi of Diya “Patrick” Lumumba, the Congolese bar owner who was accused by Knox of being the murderer but was released after being able to prove he was at his bar until 3 a.m. No trace of his DNA has been found at the murder scene.

In an interview with ABC News, Knox's parents, Edda Mellas and Curt Knox, and her 19-year-old sister, Deanna, have criticised the “media frenzy” over Knox's alleged involvement in the murder, saying the picture painted of her as “the girl from Seattle with an angel face and ice-cold eyes” who ran wild in Italy was “unrecognizeable.”

Knox has repeatedly altered her version of events, first declaring she was at Sollecito's flat on the night of the murder, but then admitting she was at the cottage and had covered her ears when she heard Kercher's screams. She later reverted to her original story.

However, her mother told ABC that her daughter had been interrogated without lawyers or interpreters while in a frightened state. “This was a horrible crime, but I couldn't understand why immediately Amanda was painted in this horrible light, where she was unrecognizeable,” she said.

Knox's sister said: “Amanda is the kindest person I know. She will do anything to make people happy and she cares about everyone else before herself.”

Knox's parents have visited her twice a week for the past three months, either together or separately. She and the other suspects can be held for up to a year before being charged.
