Prosecutor: Jail U.S. student for life

PERUGIA, Italy, Nov. 21 (UPI) -- Amanda Knox , the U.S. college student charged with killing her housemate, deserves a life sentence, an Italian prosecutor said Saturday.

Giuliano Mignini called Knox "narcissistic, aggressive, manipulative and theatrical" in his closing argument to the court in Perugia, The Guardian reported. He said Knox dealt the fatal blow to Meredith Kercher, 21, and "plunged the knife" into her throat.

Raffaele Sollecito, 25, Knox's former boyfriend, is on trial with her. Another defendant, Rudy Guede, 25, was convicted last year and given 30 years.

Both Knox and Sollecito deny killing Kercher. Knox cried as the prosecutor asked the court to convict her and impose a life sentence.

Knox, 22, of Seattle, and Kercher, from the London suburb of Coulsdon, Surrey, shared a house while studying in Perugia two years ago. Knox was a student at the University of Washington.

Mignini said Knox's reaction to Kercher's death was cold-blooded.

"In particular we should remember her doing the splits and cartwheels in the police station just after her friend had been murdered," he said.

Knox wept through much of the summation, at one point saying in Italian that Kercher was her friend.

The defense lawyers give their closing arguments Dec. 1.
