Smith was one of six people initially charged in connection with the shootout in a LaPlace mobile home park that was the deadliest assault on local law enforcement in years. Deputies Jason Triche and Brandon Nielsen were killed, and two other deputies, Michael Boyington and Jason Triche, were left severely injured.
Smith, who was convicted of being an accessory to murder, was released from the Tensas Parish Detention Facility to supervised probation on Saturday after spending nearly five years in custody.
He qualified for early release because of the state's "good time" law, which allows inmates to earn credit against their jail time by taking self-help classes and exhibiting good behavior, according to Ken Pastorick, a spokesman for the state corrections department.
