Yup, no error in that title. A citizen actually truly stopped a crime. In fact, the intended victim would be dead if said citizen didn't intervene.
According to KRQE (Albuquerque) Felix Vigil was intent upon stabbing his ex-wife (who ended up in the hospital in critical condition) when 72 year old Due Moore (not a pun! honest) shot and killed Vigil. Fortunately and against all odds, wisdom has prevailed and Moore will not be charged by the police.
