A Mills man denies his role in the shooting death of his brother.

Twenty-three year old Aaron Gish has pleaded not guilty to one count of involuntary manslaughter.

According to Mills police, in September, Gish was at home with his brother Ryan, when the gun he was handling discharged.

An autopsy report says the bullet hit Ryan in the wrist, lung, liver and heart.

In an interview with investigators, Gish said he knew the gun was loaded at the time, but was not sure why he squeezed the trigger.

He also said that he had smoked marijuana earlier in the day.

Gish remains free on $10,000 bond awaiting trial, and could face up to 20 years in prison if convicted.
