On June 6, 1983, Bank's trial began at the Luzerne County Courthouse in Wilkes Barre, Pennsylvania. Banks insisted on testifying. He said that he had only wounded some of the victims and police had killed them. Several scene witnesses, Banks family members, and Olsen testified. Olsen identified Banks as the person who shot him and left him for dead. Closing arguments took place on June 21, 1983. Banks' attorney argued that he was insane, but the jury found Banks guilty of 12 counts of first-degree murder, one count of third-degree murder, attempted murder, aggravated assault, and one count each of robbery, theft, and endangering the life of another person. On June 22, 1983, the jury recommended the death penalty.
