Arias' ex-boyfriend, Travis Alexander, was brutally murdered at his Mesa home in 2008.
Arias first told police that she didn't know what happened to Alexander, then later told police that two people broke into his house and killed him while she was staying there. Lastly, she told police she killed Alexander in self-defense.
Arias went into great detail Wednesday about how she started to feel used by her on-again, off-again boyfriend, who she said wanted her only for sex.
During her testimony, Arias continued to portray Alexander as an aggressive lover who manipulated their relationship through sex and religion.
