When St. Johns County sheriff's deputies arrived at the St. Augustine, Florida, home of Jeremy Banks on Sept. 2, 2010, they found his 24-year-old girlfriend Michelle O'Connell lying on the floor with a gunshot wound to the head. Deputies found Banks, a fellow St. Johns County sheriff's deputy, crouched at the bathroom door, clutching his phone. The gun was found on O'Connell's left with the Tac light on the firearm switched on. Later, police pictures taken at the scene revealed a shot fired into the carpet. Despite the efforts of the first responders, O'Connell was pronounced dead close to 11:48 p.m. that night.
