Carson City deputies are hoping DNA will be the key to apprehending a suspect who has been threatening a local judge.
The Nevada Appeal reports that the Carson City Sheriff's Office has issued a DNA arrest warrant, extending the statute of limitations on the case.
The warrant provides a DNA marker from an envelope sent to Justice of the Peace John Tatro but no name of a possible suspect.
Sheriff Ken Furlong said Friday that investigators have exhausted all other options in trying to identify a perpetrator.
Authorities say someone fired two shots through Tatro's front door in December 2012. No one was hurt.
In December 2014, Tatro received a Christmas card with a death threat.
In May, someone left a burning object in front of his home.
