Jodi Arias is accused of brutally murdering her ex-boyfriend Travis Alexander.  Police say she shot him in the face, stabbed him 29 times and slit his throat from ear to ear.

Cops found a camera inside a washing machine at Alexander’s home. On that memory card were pictures of Arias and Alexander in sexual poses and also pictures of a bloody Alexander as he lay dying.

Arias changed her story numerous times. First , Arias said she wasn’t there at the time, then she blamed a home invasion. Now, Arias is expected that she will say she killed her ex-boyfriend out of self-defense.

Jane Velez-Mitchell spoke to Shanna Hogan, journalist and true-crime author who was in court with Jodi Arias.
