Amanda Knox, who is internationally known for her long-running legal odyssey through the Italian judicial system regarding the 2007 murder of her British roommate, Meredith Kercher, is engaged to marry musician Colin Sutherland, reports People magazine.

The 27-year-old Seattle native has known Sutherland since middle school. The couple started dating after Knox's break up with Seattle musician James Terrano in 2014.

Knox spent four years in an Italian prison for Kercher's murder before being acquitted on appeal in 2011. Following the acquittal, she returned to the U.S. to get her life on track. She settled in Seattle and received a bachelor's degree in creative writing at the University of Washington last year. It looked like she had a bright and stable future until Italy's highest court ordered a new trial for Knox and her former Italian boyfriend, Raffaele Sollecito, in September 2013, overturning their acquittals. In January 2014, the court reinstated the guilty verdict, and in May new surveillance footage allegedly showed that Knox was at the home she shared with Kercher the night she was murdered -- raising questions about her alibi.

Knox claims that she spent that night with Sollecito at his home.

A rattled Knox told "Good Morning America," "I couldn't believe what I was hearing. I did not expect this to happen. I really expected so much more from the Italian justice system. They found me innocent once before."

The court later sentenced her to more than 28 years in prison for the 2007 murder of Kercher in Perugia.

Knox, who works as a freelance journalist and editor in Seattle, has vowed to fight the court ruling.

While waiting to learn the fate of an appeal next month, Knox can celebrate her new engagement.
