German authorities agreed Monday to extradite a key suspect in the slaying of a British university student to Italy.

Rudy Hermann Guede, a native of Ivory Coast, is wanted in connection with the sexual assault and fatal stabbing of 21-year-old Meredith Kercher, who was found dead in her Perugia apartment Nov. 2.

Guede was arrested in Germany after police caught him riding a tram without a ticket. Two other suspects, Kercher's American housemate Amanda Marie Knox and Knox's then-boyfriend, Italian Raffaele Sollecito, remain jailed in Italy in connection with the case.

Prosecutors in the southwestern German city of Koblenz agreed Monday to turn Guede over to Italy.

"The extradition can take place as soon as Italian authorities agree to a date for the handover," prosecutor Norbert Weise said in a statement.

Italian authorities say DNA tests confirm Guede had sex with the victim on the night of the slaying.

Guede's lawyer, Walter Biscotti, said Monday that he did not know when Guede would be turned over to Italy.

Guede has admitted he was in Kercher's room the night she died but said he didn't kill her and that an Italian who is trying to frame him did, Biscotti has said.
