A second defendant accused in the killing of Ryan Chaco denied the allegations he's facing in superior court. 

Frank Reyes Jr. pleaded not guilty to charges of arson, desecration, obstructing government function, and destruction of evidence before Magistrate Judge Jonathan Quan. 

Co-defendant Eithen Mendiola has since denied the murder charges he's facing. Mendiola allegedly stabbed Chaco multiple times claiming self defense. 

Reyes tried to get rid of the evidence by setting Chaco's Dededo on fire.
