Jodi Ann Arias (born July 9, 1980) is femme fatale who is known for murdering her ex boyfriend, salesman Travis Alexander on June 4, 2008. Their relationship was on-off and Jodi had discovered that Travis seeing another woman.

On June 9, a group of his friends had decided to go to his house as they were concerned.

She later changed her story and said that two intruders had broken into Alexander's home and had killed him and attacked her. She changed her story again, two years after being arrested. That time, she stated she had killed him in self defense as he had been abusive towards her.

In April 2015, she was sentenced to life without parole for murdering Alexander.
