A crowd of about 100 people were gathered early Wednesday at the scene in Berkeley, Missouri, a few miles from Ferguson, where  According to a statement from St. Louis County police spokesman Sgt. Brian Schellman, a Berkeley police officer was conducting a routine business check at a gas station around 11:15 p.m. Tuesday when he saw two men and approached them.
