Amanda Knox killed roommate Meredith, Guede tells court

Amanda Knox and her ex-boyfriend did kill Meredith Kercher, a man who was also convicted of the 21-year-old's murder has told an appeal court.

After Rudy Guede confirmed he believed the US student killed her British housemate, Knox jumped to her feet saying she was "shocked and anguished".

The hearing in Perugia is the first time that all three defendants have given evidence on the same day.

Knox, 23, and Raffaele Sollecito, 26, are appealing their convictions.

Child killer

Miss Kercher, of Coulsdon, Surrey, was found with her throat cut at her Perugia flat after what prosecutors claimed was a sex game taken to the extreme.

Knox is serving a 26-year sentence for Miss Kercher's murder while her Italian co-defendant and ex-boyfriend, Sollecito, was sentenced to 25 years.

Guede admits being in the house at the time of the Miss Kercher's murder but denies any involvement

Guede told the court that claims by a fellow prison inmate that he thought Knox and Sollecito were innocent were not true. He said he never made that claim to the inmate.

On 18 June, convicted child killer Mario Alessi told the appeal Guede had confided that Knox and Sollecito were innocent.

According to Alessi, Guede said he and a friend went to the house Miss Kercher shared with Knox with the intent of having sex with Miss Kercher and that when she refused, the scene turned violent and his unnamed accomplice slit her throat.

Drug-dealer Guede was jailed for 30 years for the sexual assault and murder of Miss Kercher after a separate fast-track trial. His sentence was reduced to 16 years on appeal.

Guede was in the witness stand as a letter he had written in response to Alessi's claims was read to the court on Monday.

"This splendid, marvellous girl was killed by Raffaele Sollecito and Amanda Knox," the letter said.

'Cursed night'

Guede has previously admitted being in the house at the time of the murder, but denies involvement in Miss Kercher's death.

After cross-examination by the defence, Guede said he had always believed Sollecito and Knox were behind the murder.

"I've always said who was there in that house on that cursed night," he told the court.

Knox stood up after Guede's evidence and denied his claims.

"The only time that Rudy Guede, Raffaele and I were in the same space has been in court. I'm shocked and anguished.

Raffaele Sollecito said his life, and that of his ex-girlfriend Amanda Knox, had been "destroyed"

"He knows we weren't there and have nothing to do with it," she said.

Sollecito said Guede was always talking "about a shadow that could be me and a voice that could be Amanda's... we've been fighting shadows for four years. Our lives have been destroyed in a subtle and absurd way."

Speaking before Monday's hearing, Knox's mother Edda Mellas told reporters she hoped that Guede would have the "integrity to stand up and tell the truth".

She said her daughter was "always very anxious and nervous but I think she's glad things are moving along. She feels things are going well," but that it is, "hard to get too hopeful, especially after the first trial."

Two other witnesses were called to counter claims made by another defence witness, a member of the Mafia named Luciano Aviello, who had told the court earlier this month that his brother - who is on the run - had killed Miss Kercher during a botched burglary.

The two witnesses - two inmates at the same prison as Aviello - testified that Aviello had said he had been contacted by Sollecito's defence team to stir up confusion in the trial in exchange for money.

Witness Alexander Ilicet said Aviello had wanted the money for a sex-change operation.
