On this day, March 6, in 1970, three members of the domestic terrorist group Weather Underground Organization were killed when a bomb accidentally exploded in the basement of a New York City house.

The four-story Greenwich Village townhouse, the former residence of a founder of Merrill Lynch and next door to the home of actor Dustin Hoffman, was reduced to a smoldering ruin.

The explosion instantly killed radicals Diana Oughton, 28, Ted Gold, 22, and Terry Robbins, 22.

Kathy Boudin, 26, and Cathlyn Wilkerson, 24, were rescued by police but escaped before questioning, landing on the FBI's Ten Most Wanted Fugitives list.

Wilkerson surrendered in 1980, and Boudin was captured in 1981 for her participation in an armed robbery that killed two police officers and a Brink's guard. She was released from prison in 2003.
