STEPHENS SAYING "All right, at this time, the court is declaring a mistrial." Jody Arias escapes the death penalty for killing her ex-boyfriend. A jury unable to agree on a sentence, meaning Arias will be sentenced to either life in prison or life with the possibility of parole in 25 years. She was found guilty of killing Travis Alexander in 2013. The Justice Department releases a scathing report on the Ferguson Police Department about seven months after Officer Darren Wilson shot unarmed teenager Michael Brown. (SOUNDBITE) ATTORNEY GENERAL ERIC HOLDER SAYING This investigation found a community that was deeply polarized; a community where deep distrust and hostility often characterized interactions between police and area residents.
