ALBUQUERQUE, N.M. (AP) - A New Mexico prosecutor has filed a motion to keep a man who killed five family members when he was a teenager detained until an appeals court decides whether to overturn his sentence.
The filing comes as Nehemiah Griego's 21st birthday on March 20 approaches. That is when he's scheduled to be released under a 2016 judge's order that found he had been receptive to treatment and could be sentenced as a juvenile, though that decision is under appeal.
Griego was 15 in January 2013 when authorities say he fatally shot his parents, and three younger siblings.
The motion Monday cites alleged "generalized" threats that prosecutors say Griego made while at a treatment facility.
A state police spokeswoman said Tuesday that agents had closed an investigation after finding no direct, criminal threats.
