A shooting at a Nebraska mall left one person dead and another wounded as terrified shoppers ran for cover.

Authorities believe the shooting at Westroads Mall in Omaha was an isolated incident, and not a random attack.

Police determined the suspects had fled the scene after searching the mall, according to Omaha police Lt. Neal Bonacci. Officers first gave the �all clear� around 1 p.m. � about an hour after multiple shots were fired, The Omaha World-Herald reports.

One man was fatally shot, while a woman suffered a leg wound, Bonacci said.

The gunfire caused panic, as people fled from the main section of the mall, according to a World-Herald reporter who was in the food court when the shooting happening.

�It was shocking,� said Alyha Wills, who was in Forever 21 with her sister when other shoppers asked if she�d heard the gunfire.

She then fled, saying, �I could hear it; it was close.�

Officials did not immediately release additional details about the suspects or what prompted the shooting.

This is the second reported shooting at Westroads Mall in a little more than a month. Omaha Police Officer Jeffrey Wittstruck was shot at four times by a 21-year-old man who was accused of shoplifting T-shirts from J.C. Penney on March 12. Wittstruck survived.

The J.C. Penney is about 200 feet (60 meters) from Von Maur , where a gunman killed eight people and himself in 2007.
