Michael Brown Death: Missouri National Guard Headed to Ferguson

The chaos in Ferguson has gotten so unruly that Missouri Gov. Jay Nixon signed an executive order deploying National Guard troops to the St. Louis suburb.

"Given these deliberate, coordinated and intensifying violent attacks on lives and property in Ferguson, I am directing the highly capable men and women of the Missouri National Guard ... in restoring peace and order to this community," Nixon said in a statement.

Gunfire, tear gas and Molotov cocktails Sunday night marked some of the fiercest clashes yet between police and protesters furious over the death of an unarmed teenager.

And the tensions continued escalating after autopsy results revealed 18-year-old Michael Brown was shot six times.
