A man with a shotgun fired randomly in a historic shopping mall Monday night in Salt Lake City, Utah, killing five people and injuring several others before he was killed, police said.

Hours later, police still were searching stores for shocked shoppers and employees who were hunkered down awaiting a safe escort from the Trolley Square mall.

"We have six fatalities and multiple victims at hospitals," police Detective Robin Snyder said. "They were found throughout the mall. I don't know male or female or ages."

At least four people were hospitalized, three in critical condition and one in serious condition, hospital spokesmen said. Two of the critically injured were a 16-year-old man and a 50-year-old man, a spokesman said.
