The Jodi Arias trial has currently cost taxpayers more than $800,000.
According to the Associated Press, since the death of Travis Alexander in June 2008, Arias originally told authorities masked intruders were responsible. However, two years later, Arias said the murder was self-defense.
Amnesia and post-traumatic stress disorder have been the most recent claims from Arias' defense team. Psychologist Richard Samuels testified for a third day on Tuesday that he diagnosed Arias with memory loss as well as PTSD.
Prosecutor Juan Martinez explained that Arias' lies affected the results of Samuels' evaluation and the test should therefore be re-administered.
Although the defense psychologist eventually said that perhaps Arias should have retaken the test, expert witnesses like Samuels will cost taxpayers more money as this trial continues.
