Lee Boyd Malvo has served almost two decades since his arrest on Oct. 24, 2002. The arrest resulted from his participation in the shooting spree within the DMV that left 10 people dead. He was 17 years old at the time of the shootings. Muhammad was 41.

Muhammad was convicted in September 2003 and sentenced to death in March 2004, and Malvo, still then a juvenile, received six consecutive life sentences without parole in Maryland and Virginia.

Now at age 37, Malvo is eligible for a reduced sentence. The ruling comes from the Maryland Court of Appeals on Aug. 26, based upon the Supreme Court guidance under the Eighth Amendment. According to Judge Robert McDonald’s order, the amendment bans life sentences without parole for juveniles “if a sentencing court determines that the offender’s crime was the result of transient immaturity,” CNN reports.
