Amanda Knox, an American exchange student accused of helping to kill her British roommate in Italy, took the stand in her own defense this week.
Barbie Nadeau, correspondent for Newsweek and The Daily Beast, says much was expected of Knox during the testimony.
"She did an excellent job," Nadeau says. "She was unflappable. She spoke first in English and after two hours she switched to Italian."
Knox, 21, and her former boyfriend Raffaele Sollecito are accused of murder and sexual violence in the slaying of Meredith Kercher, who was found in their shared apartment in Perugia, Italy, Nov. 2, 2007.
Evidence found in the house could be troubling for the defense.
"Specifically, there are five areas in the house that have her DNA and Kercher's blood mixed in the form of Kercher's blood," Nadeau says. "There's also a footprint that's been attributed to Knox in Kercher's blood outside of Kercher's bedroom."
A verdict is expected Oct. 31.
