The shooting happened at an outdoor social gathering about 12:30 a.m., said police Sgt. Eren Stephens. It happened on the city’s west side.
According to Stephens, the woman “embraced the officer from behind, causing the holstered weapon to accidently discharge.” The bullet punctured Miller’s lung and hit her heart, and she died at a hospital.
Update: over at Uncle was a link to this story; basically 'soft holster let trigger be pulled'. Which still sounds awful strange.
