On this day, June 7 … 2002: A Norwalk, Conn., Superior Court jury convicts Michael Skakel, nephew of the late Sen. Robert F. Kennedy, in the 1975 murder of Martha Moxley, Skakel’s 15-year-old neighbor, after four days of deliberations. (Skakel's conviction would be vacated in 2018 by the Connecticut Supreme Court, which ruled that his attorney had deprived him of a fair trial by failing to call an alibi witness.) Also on this day: 1769: Daniel Boone begins to explore present-day Kentucky. 1892: Homer Plessy, a "Creole of color," is arrested for refusing to leave a Whites-only car of the East Louisiana Railroad. (Ruling on his case, the U.S. Supreme Court upholds "separate but equal" racial segregation, a concept it would renounce in 1954.)
