Nashville Police say they have “exhausted all available investigative avenues” in the hunt for the person who leaked pages from a school shooter’s journals to a conservative commentator.

Emergency personnel work near the scene of an explosion in downtown Nashville, Tenn., Friday, Dec. 25, 2020. Police believe the blast was intentional but don’t yet know a motive or target, and Drake noted that officials had not received any threats before the explosion. Buildings shook and windows shattered streets away from the explosion near a building owned by AT&T that lies one block from the company's office tower, a landmark in downtown. The Federal Aviation Administration temporarily halted flights out of Nashville International Airport because of telecommunications issues associated with the explosion. McCoy said he heard gunfire 15 minutes before the explosion rocked his building, set cars in the street on fire and blew trees apart.
