Michael Aaron Fay entered the pleas during an arraignment Tuesday in Putnam County Juvenile Court. He's charged with delinquency in connection with aggravated murder.
Fay is accused of killing 17-year-old Blake Romes and 14-year-old Blaine Romes in their Ottawa trailer May 9.
An Amber Alert for all three teens was issued that day after the mother of the Romes teens discovered a gun and blood inside a trailer where the three boys lived with their mothers.
Fay told officers that the Romes brothers were dead and pointed authorities to their bodies after he was found with a stolen car in Columbus.
A prosecutor said both victims were shot once in the head.
