The defense rested its case Tuesday in the Jodi Arias murder trial in Phoenix after nearly three months of testimony, but as the prosecution was set to call a witness on Wednesday, the trial was cancelled for the day for unexplained reasons.

Defense attorneys for Jodi Arias, accused of killing her ex-boyfriend Travis Alexander in June 2008, rested their case after 2 ½ months of testimony from witnesses and experts, reports Associated Press. The prosecution had rested its case in January but was calling rebuttal witnesses to counter claims made during the defense’s testimony.

One of the main elements of the case is the portrayal of Arias, whom the defense says was abused by Alexander, suffered from post-traumatic stress disorder and was defending herself on June 4, 2008, the day Alexander was shot and stabbed to death. The prosecution argues that Arias does not suffer from any disorders and that she planned the murder.

One of the witnesses called by the prosecution, Janeen DeMarte, a clinical psychologist, testified that Arias did not suffer from PTSD or battered-woman syndrome and was scheduled to resume her testimony before the trial was cancelled for the day.

Following the afternoon recess, Judge Sherry Stephens said to the court, “An issue has arisen that will prevent us from going forward today, so I'm going to be dismissing you for the rest of the afternoon,” reports The Huffington Post. The issue, according to Headline News, was Arias suffering a migraine.

The Arias trial has drawn substantial media attention due to many sexually explicit pieces of evidence presented during testimony, including nude photos of Arias, a phone-sex recording and, while Arias was on the stand, her claims that Alexander was attracted to young boys.

In another bizarre twist, last week it was discovered Arias had a Twitter account and was tweeting via her friend Donovan Bering. On the Twitter account, Arias mostly discussed her artwork that had been available on while mentioning the trial a few times. Arias has not updated the account since April 13.

The prosecution’s testimony will resume Thursday at 12:30 p.m. EST. If convicted, Arias will face the death penalty.
