50 years ago - 1968 February 13 - Serial killer Lee Roy Martin abducts Opal Buckson, 15, as she walks to school. She will be strangled and stabbed and her nude body will be found after several days. Opal is the fourth and final murder victim of this criminal. Martin received a life sentence in a South Carolina prison but was himself stabbed to death by a fellow inmate after serving just four years.
This my opinion and to the best of my knowledge, that is, if I'm not joking.
