HLN's Dr. Drew & Dr. Casey Jordan on Jodi Arias

On Wednesday night, HLN’s Dr. Drew and criminologist/attorney Casey Jordan discussed whether it’s possible to have such a memory loss pattern without previous dissociation.

“Not only do I not buy it, I don't think anybody buys it,” Jordan said. ”There are different kinds of amnesia. There are different kinds of blackout memory. But it's rare you that get an entire gap."

She added, “If you have such a trauma, usually this kind of memory loss is caused by a … physical traumatic injury, like brain surgery or a blow to the head. None of that happened … it’s convenient memory loss.”

Dr. Drew agreed that it seemed “awfully convenient,” and further explained when it is common for people to “black out, red out or even more commonly, gray out.” Hear his full response in the video player above.

On Tuesday night, HLN’s Dr. Drew asked his special guests whether they think Arias will get death if convicted of first-degree murder.

“[Jurors] will want to, but they won't be able to do it,” attorney and criminologist Casey Jordan said. “You have 11 men and one woman. Men are simply socialized, ‘You don't do harm to women’… [but] they will have no problem finding her guilty.”
