A man shot a female seasonal employee at a busy Nordstrom store in Chicago on Friday night before turning the gun on himself, police said.

The man was pronounced dead at the scene, and the woman was taken to Northwestern Memorial Hospital in critical condition, said Officer Jose Estrada, a spokesman for the Chicago Police news affairs office.

The incident that left the 31-year-old man dead and the 22-year-old woman critically injured appeared to be related to a domestic dispute, Officer Estrada said. The man is believed to be the current or ex-boyfriend of the woman, Chicago Police Chief of Detectives John J. Escalante told the Chicago Sun-Times. The identities of the man and woman have not been released. [Update: The Chicago Tribune reports that the gunman has been identified as Marcus Dee. See below for additional details.]

The shooting at the Nordstrom store on the first block of E Grand Ave. in Chicago was reported shortly after 8:30 p.m. local time, police said. Photos posted on social media showed police responding. The store was evacuated following the shooting on Black Friday, witnesses told The Chicago Tribune. "It was a pow and a pow," alleged witness Michelle Smith said, "It was a stampede coming down the escalator," told the paper.

Update, Nov. 29 -- The Chicago Tribune reports that the gunman has been identified as Marcus Dee, 31. The woman's brother told the Chicago Sun-Times that Dee had put the woman through "months of psychological torment" prior to the shooting.
