Missouri Governor calls in National Guard after more violence Updated: Monday, August 18, 2014 FERGUSON, Missouri (NEWSCHANNEL 3) - Another round of chaos in Missouri has forced the governor to send in the National Guard."There were shootings, looting, and other acts of vandalism that clearly appear not to have been spontaneous but pre-meditated criminal acts," said Capt. Ron Johnson of the Missouri Highway Patrol. "We were walking peacefully down to the mall and a young lady was hit in her face with smoke bombs and tear gas and we were peaceful," said one protestor. Police in Ferguson say shootings, looting and vandalism are among the acts that led them to elevate their response for a second night.This escalation in violence on the heels of an autopsy report that shows 18-year-old Michael Brown was shot six times. Monday morning the streets in Ferguson were relatively quiet. It's not clear how many arrests were made again overnight.But after two weeks it seems there is little peace in this town and tensions only grew stronger with the announcement that the National Guard was moving in.Police officers in riot gear ordered people off the streets of Ferguson overnight as a second night of a mandatory midnight curfew went into effect.Just hours before, tensions continued to escalate. Authorities fired tear gas into a crowd as protesters hurled rocks in their direction. "Molotov cocktails were thrown there was shooting looting and other acts of violence. Based on these conditions, I had no choice but to elevate the level of response," said Capt. Johnson. Resident Key Smith said he was in the middle of the chaos. "My eyes were hurting, I couldn't see, I couldn't really breathe." The confrontations came amid the results of a preliminary private autopsy on Brown's body. Former New York City Chief Medical Examiner Michael Baden told the New York Times the 18-year-old was shot at least six times, including twice in the head.He said one bullet entered the top of Brown's skull, suggesting his head was bent forward when he suffered a fatal injury. Many people in Ferguson remain angry at the officer responsible for using deadly force when they believe Brown was surrendering. Ferguson police maintain Brown attacked the officer in his car and tried to take his weapon. As a sign of growing federal involvement, the Justice Department says it will conduct its own autopsy on Brown's body, as soon as possible.Because of the unrest, all schools in the Ferguson-Florissant School District will be closed Monday.President Obama has been getting regular briefings on the situation and he'll interrupt his vacation to discuss tensions between police and protesters with advisers at the White House.
