ALBUQUERQUE, N.M. (AP) — The Latest on the case of a New Mexico man who pleaded guilty to killing five family members as a teen (all times local):

12:10 p.m.

A state prosecutor is arguing that a judge failed to review several key factors in deciding to sentence a New Mexico teenager as a juvenile in the killings of five family members.

John Woykovsky with the New Mexico Attorney General's Office delivered arguments Wednesday before the state Court of Appeals. He described Nehemiah Griego's sentence as invalid.

Griego was 15 when he killed his parents and three younger siblings in 2013. He's now 20.

A 2016 ruling from a Children's Court judge cleared him for release on March 20 when he turns 21. The decision found Griego had shown he was receptive to treatment and could be sentenced as a juvenile.

The defense says the Children's Court judge had noted the crime's severity, with a reference to testimony calling it horrific.

The New Mexico Court of Appeals is set to hear arguments in the case of a man who pleaded guilty to shooting and killing five family members when he was a teenager.

The oral arguments scheduled for Wednesday in Albuquerque come nearly two years after a state children's court judge decided Nehemiah Griego had been receptive to psychological treatment while in state custody and could be sentenced as a juvenile. That decision cleared the way for Griego's release on his 21st birthday in March.

Griego was 15 when authorities say he killed his parents and three younger siblings at the family's home south of Albuquerque.

Attorney General Hector Balderas' appeal of that decision asks that the case be sent back to Children's Court for more hearings.
