A former federal prosecutor after Tuesday's hearing said the Menendez brothers will likely be freed "in a matter of months."

Lyle and Erik Menendez immediately became eligible for parole after the judge’s surprise ruling following a resentencing hearing in Los Angeles.

The two-day proceeding in L.A. ended on its first day with the judge resentencing the brothers who have spent more than three decades behind bars for their parents' 1989 murders.

The hearing will determine whether they should receive a lesser sentence, which could lead to paroled release.

Lyle and Erik Menendez have been serving life in prison without parole in connection with the killings. A state parole board could now determine if and when the brothers are released.

The brothers' battle to regain their freedom was back in court Friday, but instead of hearing why D.A. Hochman's bias against them means he needs to go, their lawyer killed the motion for withdrawal.

A resentencing hearing for Lyle and Erik Menendez included testimony from family members, a former inmate in prison and others before the judge’s decision.

Erik and Lyle Menendez will have a shot at freedom for the first time in decades after being convicted of their parents’ murder 30 years ago.
