Alleged killer Jodi Arias’ trial is being pushed back at least a week. 

At a hearing Tuesday, Judge Sherry Stephens moved the start date from November 19 to November 26. The judge has not ruled on the defense team’s request for a six-week delay. Arias’ lawyers say their expert needs more time to examine a laptop hard drive.

Court documents say the hard drive contains text messages between and pictures of Arias and the victim, Travis Alexander.

In June 2008, Alexander's roommates found his mutilated body in his shower at his Mesa, Arizona, home. Alexander, a Mormon motivational speaker, was found with his throat slit from ear to ear. According to police, he'd also been shot in the face and stabbed 29 times. Prosecutors say Arias killed Alexander after he decided to break off their sexual relationship.

Authorities say Arias has given several stories about Alexander's death. Initially, Arias told police she wasn't with him when he was killed. Then she said two intruders killed Alexander.  

Police say they found a camera at the scene showing Arias and Alexander in suggestive poses, along with photos of Alexander's dead body.

Now, Arias is saying she killed Alexander in self-defense because he got violent with her.

She faces the death penalty if she’s convicted.

The defense says this should not be a death penalty case because Arias didn’t plan to kill Alexander.

Another pretrial conference is set for November 19.
