A witness who spoke with WAVY earlier Wednesday said she believed the shooting was planned, and that the suspect was laughing at the time. Bing fatally shot six people before turning the gun on himself, police say. Three people remained hospitalized on Wednesday night, two in critical condition.

A law enforcement source told 10 On Your Side’s Chris Horne that Bing had a manifesto on his phone. The source said the manifesto described how Bing was upset about the recent change in employment status and was being harassed about it by fellow employees.

A former maintenance worker at the Chesapeake store, Joshua Johnson, told CNN that Bing had made chilling threats years before becoming America’s latest mass shooter.

“He said if he ever got fired from his job he would retaliate and people would remember who he was,” said Johnson, who worked at the store until 2019.

One staffer who witnessed the carnage, Donya Prioleau, told CNN that Bing often “said a lot of disturbing things” and was “condescending” and “quite mean to a lot of us.”

Others said he was paranoid and kept black tape over his phone camera.
