New details have emerged about the motives behind the mass shooting in Lewiston, Maine, that left 18 people dead. According to affidavits released by the Maine Attorney General's Office, the shooter, Robert Card, believed that local businesses, including Schemengee's Bar and Grill and the Just-in-Time Recreation bowling alley, were part of a conspiracy against him. Card's family also told police that he believed they were involved in the conspiracy as well. It is still unknown why Card specifically targeted these businesses, but it is believed that they were chosen because he frequented them regularly. Despite warnings from his family and others who recognized his escalating erratic behavior, Card's threats of violence were not taken seriously enough to prevent the tragedy. The shooting has raised questions about the importance of addressing mental health concerns and the need for better communication between law enforcement agencies.
