Madison Police Chief Shon Barnes gave updates to the case this afternoon, and clarified a significant detail about the school shooting. "Yesterday, after looking at the computer-aided dispatch system, it seems as if a call came from a second-grader -- it actually read, 'The call came from a second-grade teacher.' That was a mistake. That's my responsibility, and I apologize, and I clarify that today. It did not come from a second-grader -- it read 'second-grade teacher.'"
