In Chesapeake, Virginia, a gunman shot dead at least six people inside a Walmart Tuesday night. CNN reports the suspect is believed to be an employee or former employee of the store. There are reports he opened fire on other Walmart workers in a break room. Authorities have confirmed the shooter also died, possibly of a self-inflicted gunshot.

The shooting at the Walmart comes just three days after a gunman shot dead five people at Club Q, an LGBTQ+ nightclub in Colorado Springs. According to the Gun Violence Archive, there have been more than 600 mass shootings in the United States this year.
