Perugia, Italy (CNN) -- The father of American student Amanda Knox says prosecutors have "no case left," after an Italian judge rejected a request for new DNA testing of evidence. 

"It really appears to me that they want to find the truth," Curt Knox said of Judge Claudio Pratillo Hellman's decision Wednesday. "I'm very hopeful that by the end of the month, we'll be able to bring Amanda and Rafael home." 

Amanda Knox is fighting her conviction for killing her British housemate, Meredith Kercher. Knox and her ex-boyfriend, Rafael Sollecito, were found guilty of the killing in 2009. 

The judge also rejected prosecution efforts to introduce newly found records about the original testing and to hear a new witness -- all victories for Knox's defense, which opposed the motions. 

Curt Knox said his daughter is "handling it a step at a time. She's not pessimistic by any means. But she's also not saying, you know, I'm coming home." 

He told CNN that the family will be allowed to see Amanda on Friday and will have a better sense of her reaction to the court's decision then. 

Still, he acknowledged that "it was very good news for Amanda." 

Even the prosecutor's office told CNN that its attorneys are less certain of the outcome. The prosecution is still confident that the verdict will be upheld, but is aware that it could go either way, the office said. 

But Francesco Maresca, an attorney for the Kercher family, said that the rulings were not a defeat and that he understood why the judge rejected the requests.
