The death toll from the mass shooting at a Walmart in Chesapeake, Virginia, is likely to rise as a 23-year-old store worker is expected to turn off his life support machine.

Blake Williams is currently fighting for his life on a ventilator and unable to breathe on his own after he was shot by the suspected gunman and co-worker Andre Bing in Tuesday night’s massacre, according to his devastated cousin.

Bing, a 31-year-old night manager, opened fire on a co-worker in the break room just after 10 p.m., before shooting himself, police said.

Six Walmart employees died in the attack including Lorenzo Gamble, Brian Pendleton, Kellie Pyle, Randall Blevins and Tyneka Johnson. The sixth victim, a 16-year-old boy from Chesapeake, was not publicly named because he was a minor.

At least six other survivors were taken to local hospitals for further treatment, with three remaining in hospital as of Wednesday morning.

Mr Williams’ cousin Shannon Cheetham told The New York Post his younger cousin wasn’t even supposed to be working that night.

He usually works the day shift because he takes evening classes at Tidewater Community College, but has agreed to change shifts for a colleague on Tuesdays.

Now, his family is preparing to take him off life support, he said.

“He never made it home. He shouldn’t even be here. Wrong place, wrong time,” said Ms Cheetham.

The devastated 24-year-old woman told the Post about the moment she found out Mr Williams was caught up in the attack.

“I was at work and my aunt called me and I picked up the phone and her voice broke and she just screamed. Instantly I knew,” he said.

“I couldn’t even move for 30 minutes.”

Ms Cheetham paid tribute to her cousin as “fun”, “friendly” and “humble” with a “smile that lit up the room”.

He also revealed he knew Bing – the man accused of shooting his cousin dead – saying he saw him often in the Crestwood neighborhood where he grew up.

When he visited the shop where he worked, he would recognize him and “wave”, he said, adding: “You would never think someone like that would do something so extreme. Blake never spoke ill of the job or Andre.

Ms Cheetham also had mutual friends with one of Gamble’s other victims and recalls one night they “played ball” dancing in a local bar.

The motive for Tuesday night’s horror attack remains unknown but a law enforcement source told 10 On Your Side that a gruesome “manifesto” was found on Bing’s phone in the aftermath of the attack.

In his manifesto, Bing laid out a potential motive for the shooting, saying he was “upset” about the recent change in employment status and complained that he was “harassed” by fellow employees.

Several of Bing’s colleagues have also spoken out to reveal that he had had numerous “issues” with other members of staff and had displayed threatening behavior leading up to the shooting.

Joshua Johnson, a former Walmart employee who worked as a maintenance worker at the store until 2019, said the 31-year-old had given dire warnings about what he could do if he lost his job.

“He said if he got fired from his job, he would reciprocate and people would remember who he is,” Johnson told CNN.

Another former employee, who worked with the alleged gunman at the store from 2015 to 2018, revealed he was paranoid about the government watching him.

“He always said the government was watching him. He doesn’t like social media and he keeps black tape on his cell phone camera. Everyone always thought something was wrong with him,” said Shaundrayia Reese.

“He doesn’t like being recorded. He was always afraid the government would listen.”

Police were called to report active shooting at the store at 10.12pm on Tuesday night.

The first officer arrived on the scene two minutes later at 10:14 p.m. and entered the store two minutes after that at around 10:16 p.m.

Officers found the suspect dead from a self-inflicted gunshot wound in the break room along with two other suspected victims. Another victim was found dead in front of the shop. The other three victims were rushed to hospital where they succumbed to their injuries.

Andre Bing, 31, was identified as the shooter at the Chesapeake Walmart on November 22, 2022.

Police confirmed that Bing was armed with one pistol and several magazines of weapons and was wearing civilian clothes at the time of the attack.

A search warrant was issued on the suspect’s home following the shooting, with Chesapeake Police Chief Mark Solesky confirming there was “no ongoing risk to the public”.

Walmart confirmed that Bing was the store’s overnight team lead and had worked with the company since 2010.

The mass shooting marks the latest to shake America, after a gunman opened fire inside an LGBT+ nightclub in Colorado Springs, Colorado, on Saturday night.

Five people were killed and 17 others injured when suspected gunman Anderson Lee Aldrich opened fire inside Club Q in Colorado Springs on Saturday night.

The massacre ended when a heroic clubgoer knocked the shooter to the ground and held him captive until police arrived on the scene.

The five people who died in the attack were identified as Daniel Aston, Derrick Rump, Kelly Loving, Ashley Paugh and Raymond Vance.

This comes after another mass shooting in the state of Virginia on November 13, when three star football players from the University of Virginia were shot and killed as they were returning to campus from a field trip.

Fellow student and former soccer player Christopher Darnell Jones Jr., 22, allegedly opened fire on the bus.

Lavel Davis Jr., D’Sean Perry and Devin Chandler were killed in the attack, while two others were injured but survived.

Mr Jones was arrested the following day and charged with murder and other charges.

Back in 2019, Walmart stores were also the scene of another horror mass shooting. As many as 23 people were killed in a mass shooting at a store in the city of El Paso, Texas.
