Murder of Martha Moxley

Martha Elizabeth Moxley (August 16, 1960 – October 30, 1975) was a 15-year-old American high school student from Greenwich, Connecticut, who was murdered in 1975. Moxley was last seen alive spending time at the home of the Skakel family, across the street from her home in Belle Haven. The case attracted worldwide publicity, as the Skakel children were nieces and nephews of Ethel Skakel Kennedy, the widow of United States Senator Robert F. Kennedy.

Michael Skakel, also aged 15 at the time, was convicted in 2002 of murdering Moxley and was sentenced to 20 years to life in prison. Eleven years later, in 2013, Skakel was granted a new trial by a Connecticut judge who ruled that his counsel had been inadequate, and he was released on $1.2 million bail. In 2016, the Connecticut Supreme Court ruled 4–3 to reinstate Skakel's conviction. The Connecticut Supreme Court reversed itself in 2018, and ordered a new trial. On October 30, 2020, the 45th anniversary of Moxley's murder, the state of Connecticut announced it would not retry Skakel for Moxley's murder.
