A protester who advocated for peaceful demonstrations in Ferguson was charged Saturday with setting fire to a convenience store in a neighboring suburb.
A St. Louis County jail official said Joshua Williams, 19, of St. Louis, was being held on $30,000 bond. He is charged with arson, second-degree burglary and stealing less than $500.
Williams, who was frequently quoted and photographed protesting Michael Brown's death, is accused of using lighter fluid to set multiple fires inside and outside a QuikTrip in Berkeley.
Court records said Williams confessed in a videotaped interview, and that his actions were captured by surveillance video and by news media.
