BATON ROUGE, La. (AP) - A trial has ended in Baton Rouge in a federal lawsuit over medical care at the Louisiana State Penitentiary in Angola.

But it's unclear when a ruling will be handed down - and records indicate settlement efforts are possible. The judge in the case ordered both sides to file more briefs. She also told attorneys to schedule a time for post-trial mediation with a federal magistrate judge.

The class-action lawsuit was filed in 2015. It accuses Louisiana prison officials of "grossly deficient" medical care policies that have caused death and suffering at the penitentiary. The state has denied the suit's allegations.

Groups representing the prisoners include the Promise of Justice Initiative, the American Civil Liberties Union of Louisiana, the Advocacy Center, and the Southern Poverty Law Center.
