Senator Robert F. Kennedy was assassinated on this day, June 5th in 1968. It happened just after midnight at a Los Angeles hotel.

Kennedy was just 42 years old and in the midst of one of the most controversial presidential campaigns of the 20th century. President Lyndon Johnson had dropped from the race in March 1968, and Kennedy and Vice President Hubert Humphrey were heading to the Chicago convention with the nomination unsettled.

Kennedy’s convicted assassin is still alive. Sirhan Sirhan’s death sentence was commuted in 1972 after the California’s courts outlawed the death penalty. He is currently incarcerated in Pleasant Valley State Prison in Coalinga, California.
