A 37-year old woman shot and killed over the weekend in Hazelwood, Missouri has been identified as a Centralia woman.  According to authorities, Emma King Wallace was fatally shot around 2 AM Sunday, while riding in the front passenger seat of a Jeep, when shots were fired from a Mercedes-Benz that had pulled alongside the Jeep on Interstate 270 near North Lindbergh Boulevard.  The Mercedes was recovered a short time after the shooting.  It had been abandoned on Target Drive off New Halls Ferry Road.  Police said the Mercedes had been taken in a carjacking around 10:30 PM Saturday at a Sauget gas station.  Two men and a woman in their 20s and 30s were riding in the Jeep with Wallace and were wounded in the gunfire.  The male driver drove all four to Barnes-Jewish Hospital in Saint Louis.  The Major Case Squad is investigating the shooting, but at this time police say they believe the victims had just left a bar and grill on North Lindbergh Boulevard. Detectives are investigating if the shooting may have been connected with something that happened at Jay’s Classic Bar & Grill.
