Barta, who is an intensive-care nurse, said she rushed to help the young man, who had been shot in the head.

"He had a bullet lodged superficially in his temple, and his ear was bleeding," she said.

On his way into the mall, Shawn Munns' family said Talovic shot Munns, 34, in the courtyard near Green Street Social Club. Munns was heading to a car when he heard a noise and turned a little.

Munns' sister-in-law, Jodie Sparrow, said the man heard Talovic say, "Die, mother-(expletive)!" as Munns was shot twice. Munns then stumbled into the Hard Rock Cafe for help.

He was reported to be in serious condition at a hospital Tuesday but alert and talking to his family.

Salt Lake City police say Talovic entered Trolley Square's west entrance, where he shot and killed 29-year-old Vanessa Quinn in the hallway. People inside the Bath and Body Works store watched helplessly as the woman was gunned down.

"We saw him go in the back door of the mall and into the store across from Bath and Body Works, and he shot a girl right in front of the door," Madilee Puttuck said, her voice shaking with fear. She and others locked themselves in a bathroom to hide from the gunman.

Emergency dispatchers were flooded with 911 calls. So many calls were made to the Salt Lake City Police Department's 911 dispatch center that the city's overflow system kicked in, and calls started being rerouted to the Valley Emergency Communications Center. The center received approximately 50 calls from Trolley Square in a 10-to 15-minute period.

Police said Talovic next moved to Cabin Fever, a novelty and card shop, where he shot four people inside, killing three. Carolyn Tuft, 44, and her 15-year-old daughter, Kirsten Hinckley, were shot. Hinckley was killed, as were Brad Frantz, 24, and Teresa Ellis, 29.

Tuft was taken to the hospital and was listed in critical but stable condition Tuesday.

Police said Talovic also shot Stacy Hanson, 53. Hanson was reported to be in critical condition at a hospital Tuesday.

A 'hero' responds

Witnesses told the Deseret Morning News that Talovic appeared to be "hunting" people. Some described a calm expression on his face as he aimed his shotgun and fired.

Off-duty Ogden police officer Hammond, who was eating dinner with his pregnant wife at the Rodizio Grill, heard the gunfire. Walking into the mall, he spotted people on the ground — and saw Talovic.

"I noticed a man with a shotgun walking out of the business where the people were seriously injured," he said Tuesday. "He took a shot at me."

Hammond said he backed up for safety and hit the ground, losing sight of Talovic for a brief time.
