A well-known Ferguson, Mo., protester is facing felony arson charges after police say he tried to burn down a QuikTrip convenience store in Berkeley, Mo.

St. Louis County Police charged Josh Williams, 19, of St. Louis, with first-degree arson, second-degree burglary and stealing under $500. They say that on Dec. 24, Williams started "multiple fires inside and outside" the QuikTrip store and "recklessly" placed nearby people in serious danger. He also stole a lighter, some gum and cash, police say.
