After four years in Italy, most of that time spent behind bars, Amanda Knox returned home to Seattle, Washington on Wednesday.

Knox, who on Monday was acquitted of the murder of Meredith Kercher in Perugia, said she was overwhelmed by her welcome and thanked everyone who supported her during the whole ordeal.

People watching the press conference cheered and shouted welcome home, Amanda to encourage her onto the podium.

I'm really overwhelmed right now. I was looking down from the airplane and it seemed like everything wasn't real. Knox said.

What's important for me to say is just thank you, to everyone who has believed in me, who has defended me, who has supported my family, she said.

Knox flew into Seattle-Tacoma International Airport from Rome on Tuesday, after leaving Perugia in Umbria immediately after she was checked out of prison.

In 2009, Knox was found guilty of murdering her flat mate, Kercher, also a student. Knox's boyfriend Raffaele Sollecito was also convicted, and the two were sentenced to 26 and 25 years in prison, respectively.

After a ten month-long appeals trial, both were acquitted of the four-year-old crime and freed.

The verdict on Monday was delivered one-and-a-half hours after the promised 8 p.m. deadline, an indication that the jury did not have an easy time with the decision.

Earlier that day, Knox gave what would later become her final address to the court, saying again that she didn't kill Kercher. In the passionate and emotional speech, Knox said that she wants to find justice over her friend's murder as much as anyone, but that the last four years have changed her forever.

I didn't rape. I didn't steal. I was not there, she said in Italian. We had a good relationship. We were all available to each other. I shared my life, especially with Meredith. We had a friendship. We were friends. She was concerned for me. She was always kind to me. She cared about me.
