The hearing was reportedly to take place so Judge Sherry Stephens could determine whether testimony from psychologist Richard Samuels about premeditated murder and crimes committed under the heat of passion would be allowed.
According to HLN, Arias’ attorneys want the forensic specialist to talk about research that explains the differences between the two types of crimes.

On Thursday, psychologist Richard Samuels testified for the defense, saying Arias is basically a peace-loving woman who does not have clear memories of what happened on the day Alexander died because she is suffering from post traumatic stress disorder.
The hearing is now slated to take place on Monday afternoon, reports HLN.
On Friday, a bizarre police surveillance video was released that shows Arias just 15 minutes after crying during a police interview involving Alexander’s death, laughing, singing, and doing a headstand. Only minutes later, she was charged with his murder.
Arias, 32, is charged with the 2008 murder of Alexander, 30. He was stabbed over two dozen times, was shot in the head, and his throat was slashed. She claims she killed him in self-defense, but during the trial Arias has testified she does not remember much about the confrontation the two had that eventually led to his death.
