The notorious Menendez brothers case came back into the spotlight this year when Netflix released a scripted series and a documentary, both of which added momentum to Erik and Lyle Menendez's push to be released from prison.
The brothers -- who were convicted in the 1990s for the 1989 murders of their parents, Jose and Kitty Menendez -- have three possible paths to freedom.
One path is through resentencing. The Los Angeles County district attorney announced in October that he was recommending the brothers' sentence of life without the possibility of parole be removed, and they should instead be sentenced for murder, which would be a sentence of 50 years to life. Because both brothers were under 26 at the time of the crimes, with the new sentence, they would be eligible for parole immediately.
The third path is the brothers' request for clemency, which they've submitted to California Gov. Gavin Newsom.
