Residents and activists took to the streets at the weekend in Missouri, to protest another killing of a black teenager by a police officer. A 32-year-old white St. Louis police officer fatally shot 18-year-old Vonderrit Myers Jr. after the officer, who was off-duty and working for a private security company, saw Myers and two friends running and pursued them, according to a statement issued by the St. Louis police department.
