Delling pleaded guilty of murdering University of Idaho student David Boss in Moscow and Bradley Morse in Boise, and he was sentenced to life in prison without parole. Delling appealed the court's decision based on the fact that he suffers from acute paranoid schizophrenia, and Idaho does not recognize a defense of insanity.
"Insanity's always a factor," said Latah County Prosecuting Attorney Bill Thompson. "And it's going to come into factor for what happens with the case. But it's not an excuse for committing a crime, because in Idaho, what's most important is protecting our citizens."
Thompson said that he's pleased that the Supreme Court chose not to hear the case because it's just one more step to getting the victims some closure.
Delling's attorneys questioned the constitutionality of Idaho's law and appealed the case to the Supreme Court with the hope that Delling would receive a lesser punishment due to his mental illness. Medical experts officially diagnosed Delling as a schizophrenic, and expert witnesses for the defense testified Delling was driven to violence by a delusion caused by the illness.
