The murder of a Hispanic New Mexico jailer in 1968 — a year of unrest in the U.S. — has divided residents, scholars and civil rights advocates for decades. Fifty years and two investigations later, one of the most dramatic conflicts of the civil rights era remains unsolved. "I think whoever did it probably went to his grave," Maria Varela, a photographer who worked with civil rights activists in the area, said of the killing. Their actions helped spark the Chicano Movement — a militant phase of the Mexican-American civil rights struggle. In fact, scholars have uncovered evidence authorities were trying to provoke Tijerina and his group into a violent confrontation.
