Police detective Cory Golightly was put on administrative leave after accidentally shooting his own mother at a wedding in Kentucky.The weapon is described as a .38 caliber revolver. I'm pretty dubious about his story, given the design of revolvers over the past 50+ years. It is more likely he was fiddling with it in his pocket--cocking and uncocking it--when it discharged.
The 32-year-old officer was adjusting his jacket when the weapon fell out and fired through the holster when it hit the ground.
