Deputy Puckett missed her shift at work on Sunday afternoon, prompting a colleague to drive by her house in Springfield, Tennessee. 

When the colleague arrived, Puckett's home was on fire. The fire department responded and made entry into the home, where they found Puckett suffering from at least one gunshot wound. She was pronounced deceased at the scene.
