Execution trial: A judge ruled Monday that Jodi Arias can represent herself in the upcoming penalty phase of her murder trial, where jurors will decide whether she is put to death for killing her ex-boyfriend. Arias, 34, was convicted of first-degree murder last year in the 2008 killing of Travis Alexander, but jurors couldn't reach a decision on sentencing. Under Arizona law, while Arias' murder conviction stands, prosecutors have the option of putting on a second penalty phase with a new jury in an effort to secure the death penalty. Arias will now have the task of arguing a death penalty case just four weeks from now despite having no legal experience and no college degree or high school diploma. Arias got her GED in jail.
