The jury, which consisted of seven men and five women, began its deliberations on Wednesday after nine days of testimony. The verdict came on the second day of deliberations.
Wafer, 55, was charged with second degree murder and manslaughter for shooting and killing McBride, 19, last November when the teenager showed up inebriated on his porch at 4:40 a.m. The jury found him guilty of second degree murder.
He will be sentenced Aug. 21 and could face a maximum of life in prison with parole.
Wafer said he could only make out a figure around his house, said the person pounded on his door and made him fear for his life.
When the jury began its deliberations, they immediately made several requests, including to have Wafer’s shotgun and his screen door brought to the jury room.
The screen door is comprised of a steel frame with a screen insert held in place by clips. Investigators found the screen insert out of position when they arrived on the shooting scene, according to testimony.
The defense argued that the screen was awry because of the way because McBride pounded on the door. Prosecutors told the court that the screen could have slipped out of position days or weeks before the shooting and there was no evidence it was caused by McBride.
Under a 2006 Michigan self-defense law, a homeowner has the right to use force during a break-in. Otherwise, a person must prove his or her life was in danger.
