Amanda Knox was pictured enjoying herself at a cocktail party after she arrived in Italy for the first time since she was released from prison in the country in 2011.

Knox, 31, will speak at a conference for wrongly-convicted crime suspects this weekend, seven and a half years after she fled Italy when her own conviction for murdering British student Meredith Kercher was overturned.

Shying away from cameras as she touched down in Milan, the writer and campaigner kept her head bowed as she left the airport and she was joined by her fiancé Christopher Robinson and her mother.

But the 31-year-old seemed to cheer up at a cocktail party on the eve of the opening of the Criminal Justice Festival at the Law University of Modena, in northern Italy.

Her arrival comes as she penned an essay on Medium about her return to the country,  saying aged 24 she ‘fled the country in a high-speed chase, paparazzi literally ramming the back of my stepdad’s rental car’.

The former exchange student, who spent four years in Italian prison after she was wrongly convicted of the murder of her roommate Meredith Kercher, can be seen  clutching her passport in the photos. 

Speaking about her wrongful conviction in an essay published yesterday, Knox said prior to her trial she thought her ‘innocence was a guarantee of her freedom’.

‘I was wrong. The moment I was acquitted was just as insane. I had prepared myself to grow old in prison. I’d forgotten what it was like to walk on grass’ she penned.

On Sunday, the 31-year-old took to Instagram to share her uneasiness in the days leading up to the trip by posting a photo of herself clinging to the side of Rattlesnake Ledge in Washington State.

Amanda Knox shared an Instagram post Sunday night revealing the anxiety she is feeling as she prepares to return to Italy for the first time since getting out of prison eight years ago. In the caption of the photo taken at Rattlesnake Ledge in Washington state, Knox wrote: ‘3 Days till I return to Italy for the first time since leaving prison. Feeling frayed, so I made my own inspirational workplace poster. “Hang in there!” Just imagine I’m a kitten’

Knox announced last month that she would be discussing ‘trial by media’ at an event hosted by the Italy Innocence Project in Modena on June 14 and 15.

‘I’m honored to accept their invitation to speak to the Italian people at this historic event and return to Italy for the first time,’ she said.

Speaking candidly about the surreal moments in her life Knox wrote in the online essay that she’d been approached by a woman who apologised for treating her as entertainment during her trial.

'I'm honored to accept their invitation to speak to the Italian people at this historic event and return to Italy for the first time,' she said

She said that she had hope in the wake of the 2016 Netflix documentary about her case.

‘Of all the surreal moments in my extremely surreal life, the one that brings me the most hope right now, while I’m polishing up the speech I’m about to give to a potentially hostile audience in Italy, came in the wake of that Netflix documentary. 

‘A woman approached me, crying, after I gave a talk, and she said something I’d been told before on Twitter. I wish I could say it’s been thousands or even hundreds of people who have tweeted the sentiment at me, but it has only been a few dozen. Still, hearing this woman say it to my face, it shocked me.

‘She said, “I’m sorry. I’m sorry I treated you as entertainment.”‘ 

Knox has always maintained her innocence, insisting that she and Sollecito had spent the evening together at Sollecito's home watching a film, smoking marijuana and being intimate

She is now engaged to fiancé Christopher Robinson, a novelist who proposed to Knox with an elaborate sci-fi-themed display last November.

They have been dating since February 2016 and Knox made the relationship public with a change in her Facebook status later that year.  

The couple met after Knox – who became known as Foxy Knoxy during her ordeal – had reviewed Robinson’s book, War of the Encyclopaedists, on her blog.
