McKinney's trial took place in October and November 1999. Prosecutor Cal Rerucha alleged that McKinney and Henderson pretended to be gay to gain Shepard's trust. Price, McKinney's girlfriend, testified that Henderson and McKinney had "pretended they were gay to get [Shepard] in the truck and rob him." McKinney's lawyer attempted to put forward a gay panic defense, arguing that McKinney was driven to temporary insanity by alleged sexual advances by Shepard. This defense was rejected by the judge. McKinney's lawyer stated that the two men wanted to rob Shepard but never intended to kill him. Rerucha argued that the killing had been premeditated, driven by "greed and violence", rather than by Shepard's sexual orientation. The jury found McKinney not guilty of premeditated murder but guilty of felony murder and began to deliberate on the death penalty. Shepard's parents brokered a deal that resulted in McKinney receiving two consecutive life terms without the possibility of parole. Henderson and McKinney were incarcerated in the Wyoming State Penitentiary in Rawlins and were later transferred to other prisons because of overcrowding. Following her testimony at McKinney's trial, Price pleaded guilty to a reduced charge of misdemeanor interference with a police officer.
