List of Famous people who died at 15

Martha Elizabeth Moxley was a 15-year-old American high school student from Greenwich, Connecticut who was murdered in 1975. She was last seen alive spending time at the home of the Skakel family, across the street from her home in Belle Haven. Michael Skakel, also 15 at the time, was convicted in 2002 of murdering Moxley and was sentenced to 20 years to life. In 2013, he was granted a new trial by a Connecticut judge who ruled that his counsel had been inadequate; Skakel was then released on $1.2 million bail. On December 30, 2016, the Connecticut Supreme Court ruled 4–3 to reinstate Skakel's conviction. The Connecticut Supreme Court reversed itself on May 4, 2018 and ordered a new trial. On October 30, 2020, the state of Connecticut announced it would not retry Skakel for Moxley's murder.

Janice Marie Young was a formerly unidentified American girl who was pushed into the path of a moving vehicle on June 9, 1973.
