Zachary Ballinger pointed a semi-automatic rifle at his friend Austin Michael Hermann, the Adams County State's Attorney said.
He fired one round killing Hermann, Adams County investigators said.
Ballinger, 21, of Quincy was arrested Sunday after the early-morning shooting on the front porch of a home in the 3000 block of South 24th Street.
Deputies found 21-year-old Hermann there shortly after 5:15 a.m. a single gunshot wound. A neighbor called deputies after hearing what sounded like gunshots.
"The elements of the offense are that, in performing an act recklessly, he caused the death of someone," State's Attorney Jon Barnard said. "In this case, that means he pointed an AR-15 at the victim and discharged the firearm."
The Adams County Coroner pronounced Hermann dead at 5:57 a.m. Sunday.
Ballinger made his first court appearance late Monday morning.
Family members and friends were present when Ballinger was brought into the courtroom. Several family members wiped the tears from their eyes throughout the proceedings.
He's charged with involuntary manslaughter. He faces between two and fine years and a possible $25,000 fine.
He's also charged with possession of cannabis with intent to distribute more than 500 grams but less than 2,000 grams. He faces between three and seven years in state prison and a $100,000 fine.
Ballinger was arrested early, Sunday in the fatal shooting.
The prosecuting attorney asked for a $50,000 bond. Ballinger's defense asked for a $20,000 bond. The judge denied the lower bond citing the intent to distribute charge.
As Ballinger left the courtroom, one family member cried out â??I love youâ??.
â??I think the most obvious is its a tragedy, an avoidable tragedy, I think that says it all.â?? Adams County State's Attorney Jon Barnard said.
Ballinger is due back in court April 8.
