Chesapeake City Manager Chris Price said Wednesday that he was "very, very proud of the response of our public safety team" after the mass shooting at a Walmart.

"You hope a day like this never comes, but you train for it," Price said during a press conference. "We practice, we talk about it, we discuss, we learn lessons from other places, we try to put those lessons to good use, hoping those lessons will never have to be put to good use."

Price described Chesapeake as a "wonderful place" where the community comes together "when times are good" and "when times are difficult."

"I know it pains all of us to be together today on this day of incredible tragedy and unimaginable sadness," he added.

Price then read a statement from Chesapeake Mayor Rick West, who tested positive for COVID-19 and could not attend the press conference.

"I am devastated by the senseless act of violence that took place late last night in our city," Price said, quoting West’s statement. "My prayers are with all those affected -- the victims, their family, their friends and their coworkers. I am grateful for the quick actions taken by our first responders who rushed to the scene. Chespeake is a tighknit community and we are all shaken by this news. Together, we will support each other throughout this time. Please keep us in your prayers."

The mayor as well as the city council have all been fully briefed on the shooting and the response, according to Price.

In addition to the six victims killed, four people were wounded in Tuesday night's shooting at a Chesapeake Walmart, according to police.

"While our investigation continues we can tell you the following: six victims have died, four victims are in area hospitals with conditions unknown at this time and the suspect is dead from what we believe is a self-inflicted gunshot wound," Chesapeake Police Chief Mark Solesky said during a press conference on Wednesday morning.

While police believe the suspect was a current employee of the store, Solesky would not confirm whether the victims were all employees as well. He told reporters that it’s unclear whether the shooting was a targeted or random attack.

Preliminary information indicates a gunman walked into the break room of a Chesapeake Walmart and opened fire at people before shooting himself, law enforcement sources told ABC News.

The suspect was an employee of that store and, possibly, a manager, according to the sources.

Law enforcement sources also told ABC News that authorities are investigating whether the shooting was a case of workplace violence.

The suspect in Tuesday night's mass shooting at the Walmart on Sam's Circle in Chesapeake is believed to be a current employee and appears to have died from a self-inflicted gunshot wound, according to Chesapeake Police Chief Mark Solesky.

"We have reason to believe that there's no risk to the public at this time," Soleksy said during a press conference on Wednesday morning. "We cannot tell you the identity of the shooter because his next of kin has not been notified."

Police received the initial 911 call at 10:12 p.m. local time. Officers responded to the scene within two minutes and entered the store at 10:16 p.m. local time, where they found the deceased suspect and multiple victims. A pistol was recovered and the scene was declared safe by 11:20 p.m. local time, according to Soleksy, who described the shooting as "senseless violence."

"This investigation is still ongoing, so there's no clear motive at this time," he told reporters. "We'll be processing that scene for days."

Walmart employee Briana Tyler said she was with her co-workers in the break room around 10 p.m. when the gunfire broke out.

"My manager just opened the door and he just opened fire," Tyler told ABC News. "He wasn't aiming at anybody specifically. He just literally started shooting throughout the entire break room and I watched multiple people just drop down to the floor, whether they were trying to duck for cover or they were hit."

Tyler said the gunman looked "directly at" her and fired, but "luckily missed" her head by "an inch or two."

"He didn't say a word, he didn't say anything at all," she said. "He just came around the corner and started shooting. The first person that was in his eyesight, he shot him down.”

In another interview with ABC News later on Wednesday, she said the suspect, identified as 31-year-old Andre Bing, "was quiet and to himself" and "gave off ... the loner type."

"I've never once had, like, a joyous, fun conversation with him. It was always about work and that was it," she explained. "With everybody else, you know, a lot of people will, they laugh, they joke, I have other supervisors that I can, you know, talk to casually. But with him ... he wasn't like the fun, bubbly type of person."

Tyler, 28, is a mom to a 4-year-old son.

She said the shooting “taught me that life can literally be taken from you at the blink of an eye,” even when “doing something as innocently as trying to go to work.”

“So I would just say just reach out to the ones you love, keep an open relationship with them, do your best … because at the end of the day, you genuinely never know when you will look your child or your mother in their eyes again,” she said.
