Amanda Knox tearfully thanks supporters as she returns to Seattle

The day after her acquittal, Amanda Knox attended a press conference upon her arrival at Seattle ’s Tacoma international airport.

Not without emotion, she thanked those who supported her in the past four years.

“They’re reminding me to speak in English, because I’m having problems with that,” Knox said, her voice trembling. “I’m really overwhelmed right now. I was looking down from the airplane, and it seemed like everything wasn’t real.”

“What’s so important for me to say is just thank you, for everyone who’s believed in me, who’s defended me, who’s supported my family,” a sobbing Knox said. “My family’s the most important thing to me right now, and I just want to go be with them. So thank you for being there for me.”

“The first things [Amanda will do] I think will be some of the simplest things like you know laying down in some grass,” her father Curt Knox told reporters who had gathered outside his home.

“She’s been in a concrete prison for four years, and the simplest things that you take for granted she hasn’t had… and then she’ll try to just start re-adjusting, reconnecting with all of her friends and family, and stuff like that,” he said, politely declining to discuss where he was headed.

“The focus simply is Amanda’s well-being and getting her re-associated with just being a regular person again,” he said. “What’s the trauma … and when will it show up, if it even shows up? She’s a very strong girl, but it’s been a tough time for her.”

“Let us not forget that Meredith was Amanda’s friend, and I know Amanda and the family wants you to remember Meredith and to keep the Kercher family in your prayers,” Theodore Simon, the Knox family’s U.S. legal adviser, told those who had gathered to welcome Amanda.

Before being acquitted, Amanda was sentenced to 26 years in prison for the murder of her roommate Meredith Kercher in November 2007.

Prosecutors in Italy will lodge an appeal and a new trial could be held in 2013 but probably without Amanda Knox, as the United States don’t extradite their citizens prosecuted abroad.
