Jodi Arias' first-degree murder trial resumes on Monday for the 2008 Arizona killing of her ex-boyfriend Travis Alexander.

The trial can watched via the free live stream below. 

Arias' defense expert, PhD psychologist Richard Samuels, is expected to return to the witness stand after he answered over 100 questions by the jurors last week. Arizona is one of the few states that allows jurors to submit questions. Earlier in the trial, the jury submitted over 220 questions for Arias in the last few days of her testimonies. All juror questions were read aloud by Judge Sherry Stephens.

The jury questioned Samuels' claim that Arias has Post-Traumatic Stress Disorder. They also asked about her lies, amnesia, low self-esteem and other questions to determine if Alexander's death was pre-meditated. When Samuels testified on March 14 that Arias has PTSD, he supported her "foggy" memory issues and claimed it is the reason why she cannot recall how and exactly when she stabbed her victim at least 27 times.

On March18, the defense expert supported the diagnosis again when he testified that Arias experienced memory loss brought on by severe trauma and stress. Prosecutor Juan Martinez undermined Samuels during his cross-examination that day. He said because Arias lied many times, she does not have PTSD.

Samuels' credibility was questioned again by Martinez after he answered the jury questions on March 21. It was another round of questioning from Martinez who cross-examined the defense expert on last week Monday, Tuesday and Wednesday. Through intense questioning, Martinez brought up several inconsistencies in Arias' tale of events that took place the day she killed Alexander. He also revisited her stories that Alexander pressured her to have sex too quickly.

On March 19 Martinez read an article out loud in the Maricopa County court room that said one of the tests Samuels gave Arias to take, the MCMI exam, should not be used in the court of law. The prosecutor said a day earlier that because Samuels is a PhD not an MD, he may not be qualified to use the Post-traumatic Stress Disorder diagnosis to support Arias' "foggy" memory claims.

Arias is charged for the brutal 2008 murder of her ex-lover Alexander, a 30-year-old Mormon motivational speaker. Arias stabbed her victim over 27 times, slit his throat from ear to ear and shot him in the head. His body was discovered the day he was killed: June 4, 2008. Arias lied twice at first about how he died and later admitted that she killed him in an act of self-defense.

Watch the live stream of Arias' murder trial on Monday beginning at 12:30 p.m. EST.
