On the night of September 24, 1982, Banks drank large quantities of straight gin and took prescription drugs at his home on Schoolhouse Lane in Wilkes-Barre, Pennsylvania. The next morning on September 25, 1982, he used an AR-15 semi-automatic rifle to kill eight people in his house, including three women in their 20s (all girlfriends and mothers of his children) and five children, four of them his. Two of the women were sisters. Banks dressed in military fatigues and went outside, where he saw 22-year-old Jimmy Olsen and 24-year-old Ray Hall, Jr, who were leaving a house across the street. He shot at them both, reportedly yelling that they "would not tell anyone about this," before he fired. He hit both men, fatally wounding Hall; Olsen survived. Banks drove away.
