Knox vows she will prove innocence over killing

AMANDA Knox spoke yesterday of her battle to prove she did not kill her British flatmate Meredith Kercher.

The American student was found guilty along with Italian former boyfriend Raffaele Sollecito in December of killing Miss Kercher, but said she will “fight to prove” she is innocent.

She also revealed she exchanges letters with 26-year-old Sollecito, who is being held in a different prison.
