Gillis said she tested three guns taken from Downs’ Auburn home during a February 2019 police search.
She ruled out a rifle as being the possible murder weapon. She said she couldn’t eliminate a Ruger and an H & R pistol owned by Downs as the gun that fired the lethal bullet, but said the Ruger was less likely.
Asked by Assistant Attorney General Chris Darnall whether the H & R pistol could have fired the bullet, Gillis said, “Yes, the individual characteristics and class characteristics that I see all correspond.” But, she added, “it’s not enough for an identification” due to the extensive damage sustained by the bullet.
