A New Jersey man who saw his doctor about depression and insomnia began taking Zoloft and Ambien. He then decided to polish his.38 caliber Colt revolver. The rest almost seems incredulous. Robert Buck reportedly fell asleep while ‘inspecting’ his gun. It lay in his right hand until he thought he heard the phone ring, and reached over with his left hand to get it. The gun went off, and Buck took a bullet to.
