Police told NBC10 two customers were arguing inside the store when one of them pulled out a gun and fired five to 10 shots. A Walmart employee was shot once in the calf, according to police. “I could see something ricochet to the floor and then it like flashed. So, I’m assuming that was the bullet,” a woman, who did not reveal her full name, told NBC10. “Then they rushed everybody to the back of the store.” The woman told NBC10 children were inside the Walmart at the time of the shooting. “Children screaming,” she said. “One woman, she was hyperventilating. She was panicking. I went to her side. I was telling her to breathe. Take deep breaths so she could be able to think and concentrate.” Another woman – who also did not reveal her full name – told NBC10 she was with her 3-year-old son inside the store when the shots were fired. “I was waiting to pay. And the crazy part about it is, my friend was like, ‘Oh let’s go to that aisle.’ I was like, ‘No, I don’t want to go.’ I was just like, ‘I don’t know why they want to go to that aisle,'” she said. “And that’s where it happened. So I don’t know, the prayer I prayed before I went outside today was a good one.” The employee was taken to the hospital. Police said her injury is not life-threatening and she’s expected to recover. Witnesses said more employees rushed customers to safety and that they sheltered-in-place inside the store for about an hour. “They say you don’t know how strong you are,” the second witness told NBC10. “But to be strong is your only option.” A photo of a shattered glass door outside the Walmart. Police said the gunman left the store and remains on the loose. An officer told NBC10 the public in the immediate area should not be concerned, however, and described the shooting as an isolated incident. Police have not released a detailed description of the suspect, only saying he was a Black male wearing an orange hooded sweatshirt and gray sweatpants. The officer said police plan to release a photo of the suspect and more information on the shooting at some point Saturday morning. This story is developing. Check back for updates.
