A woman who was shot by her ex-boyfriend at a busy Nordstrom store on Black Friday has died a day after the attack.

The 22-year-old, who was a seasonal worker at the downtown Chicago branch, was gunned down by Marcus Dee, 31, on Friday before he turned the gun on himself.

Her family have revealed that Dee, who was declared dead at the scene, put the woman through months of 'psychological torment'.

They had flown in especially to surprise the law student, who was studying at the University of Chicago, for her birthday. She had taken the job so she could afford tuition fees.

The woman's brother told the Chicago Sun-Times: 'I would say there was a lot of emotional traumatizing phrases and words. It was a very strange circumstance.'

The victim's sister told the paper that the pair had been dating between August 2012 and December 2013. She claimed he had been abusive throughout the relationship and after the break-up.

They tried to get legal protection after Dee constantly called and texted the entire family.

The woman also changed her number several times after Dee would ring up and threaten to kill himself.

At one point Dee tried to file a restraining order against the woman, but the request was denied by a judge.

Crowds in the upscale department store were sent into a panic as they heard gunshots on the second floor and hurried out of the building.

Hundreds of shoppers were inside at the the time for the Black Friday sales.

Suzanne Nanos-Gusching was on the third floor with her daughter who was trying on a dress for a sorority formal at the University of Michigan when shots rang out.

'We just saw people running out and they (the employees) rushed her to get dress,' he told the paper. 'They were adamant about getting us out of the building.'

Janis Tillman who was in the store at the time told NBC Chicago:

'I was right around the corner when an eyewitness came out. I said, 'What happened?' She said, 'I saw somebody.. I saw the guy pull out a gun, shot her, and then he then shot himself.' She was shaken. Very shaken.'
