Prosecutors in Arizona will today begin arguing that 32-year-old Jodi Arias should receive the death penalty for the murder of her ex-boyfriend, Travis Alexander, who was killed in June 2008.
Alexander, a 30-year-old Mormon motivational speaker, was found stabbed 27 times, with his throat slit and with a bullet in his head at his home in Mesa, Arizona days after the savage attack.
Arias, a photographer who had dated Alexander for nearly five months in 2007, has been in jail since her arrest. She has pleaded not-guilty to first degree murder.

But investigators and Alexander's friends maintain that Arias became bitterly jealous and 'obsessed' with him after the break up, and even stalked him in the months leading up to his death.
The couple had met at a work conference in Las Vegas in September 2006 and began speaking on the phone every day. Court records show they exchanged as many as 82,000 emails.
In June 2008, Alexander told friends he thought Arias might have hacked into his Facebook account and told her to stay away.

Yet on June 4, she visited his home and they had sex before he was murdered. She later told police that they had maintained a secret sexual relationship despite breaking up, ABC reported.
'There's nothing about her that I see in marriage material - or wife material,' Alexander had said, according to his friend, Dave Hall. 'But it's hard to say no to a woman that sneaks into your house, crawls in your bed and tries to, you know, seduce you.'
At first she denied being at his house the day he was killed, yet police found a camera in Alexander's washing machine containing graphic pictures of the pair having sex.
The water-logged camera, which belonged to Alexander, had been damaged in the washing machine, but the Mesa police crime lab was able to recover images, some of which had been deleted.
Among those deleted were pictures showing Alexander posing naked in the shower at 5.22pm, with the last picture showing him alive at 5.30pm. Later photos showed him bleeding while on the floor.
The camera also contained pictures of Arias posing naked on Alexander's bed at 1.40pm.
On June 9, his friends went to his upscale home after he had failed to return their calls. They found him dead in his shower and his body was 'well into the decomposition process'.
Wounds show that Alexander attempted to fight back, court records show. An autopsy found he sustained 27 puncture wounds and one gunshot wound, with the bullet found in his left cheek.
Investigators also found a bloody left palm print with Arias' DNA on the bathroom wall. Her DNA was also found in hair recovered from a bloody wall, according to the Arizona Republic.
After initially claiming that she had not been at his home that day, Arias changed her story to admit she had been there - but had not killed her ex-boyfriend.
She later changed her story once again, telling the court that she killed Alexander in self defense after he became angry when she dropped his camera.
She claims he had been sexually and physically abusive throughout their relationship.
'It makes me sick because I know her true side,' Steven Alexander, Travis Alexander's brother, told ABC. 'And I ask people to please not buy into this sweet innocent personality that she puts on.'
As well as the inconsistencies in her story, Arias' case has been plagued with difficulties with her legal representation.
She asked to represent herself but when she submitted letters to the court that she claimed Alexander had written - saying he was a pedophile - they were found to be forgeries, and she told a judge she was in 'over her head'.
