(AP)--Hearings are scheduled this week to determine whether three people convicted of some of North Carolina's most notorious killings can be taken off North Carolina's death row under the Racial Justice Act.

The Fayetteville Observer reported the inmates want their death sentences lessened to life in prison under the act, which allows appeals if it's proved that racial bias was a factor in their sentencing.

They are Tilmon Golphin, a 34-year-old black man; Quintel Augustine, a 34-year-old black man; and Christina Walters, a 33-year-old American Indian woman.

Golphin killed a state trooper and a sheriff's deputy, and Augustine murdered a police officer. Walters killed two women in a gang-initiation ritual.

Earlier this year, Marcus Reymond Robinson became the first prisoner removed from death row under the law.
