Dylan Fisher, 19, is facing several charges, including reckless conduct with a dangerous weapon and endangering the welfare of a child with a dangerous weapon.
Police said he and his stepfather, James Utely, began arguing in January because Fisher held a party while Utley was trying to sleep. They said Utley was charged with domestic aggravated assault after he allegely hit Fisher in the head with a baseball bat.
Fisher is accused of then grabbing a gun and shooting it in the home while others were present, including his 6-day-old child. He also was indicted on two counts of tampering with a witness.
