Erik and Lyle Menendez 's much-anticipated resentencing hearing will be held Tuesday and Wednesday with lawyers set to battle over whether the brothers should get a lesser sentence, clearing the way for a potential release from prison. Defense attorney Mark Geragos, who is pushing for their release, said he plans to call seven witnesses.

A Los Angeles judge will preside over the resentencing hearing that is expected to last two days. If he shortens their sentences, the brothers would still need approval from the state’s parole board to get out of prison. They could then potentially go free on time served.

After seven months of hearings, court filings and news conferences, Lyle and Erik Menendez faced their first possibility of freedom Tuesday as a two-day resentencing hearing got underway, three decades after they were convicted of the 1989 murders of their parents.
