Insights and Calls for Action on Louisville Gun Violence.

The family of Connor Sturgeon, the gunman who killed five colleagues and injured nine others in a Louisville bank office on Monday, said he had "challenges" with his mental health but seemed normal the day before the attack. Sturgeon's roommate called his mother to say he had left a disturbing note behind, and she called 911. Sturgeon texted his parents a message saying that he loved them before heading to work with an AR-15 he had purchased legally a week earlier. Sturgeon suffered multiple concussions playing football in high school, which some believe may have led to later issues.
