Wallace’s family explained he had been unable to sleep because of the noise which impacted his ability to work and his health.
Not believing Wallace was being genuine in his efforts to move forward from the incident, Casey decided to take matters into his own hands.
According to the affidavit, Casey armed himself with a military-styled knife and Taser under his blanket before opening the door and fatally stabbing Wallace three times in the chest.
Casey’s defence attorney James Lyons said in court there were multiple threats made against his client’s life.
He described Casey as “a really good man who was not equipped to deal with this type of sustained abuse and threats.”
“He was terrified of this guy, and he believed that he had no option,” Lyons said.
Casey’s lawyer also argued his client was autistic which made it difficult for him to deal with the confrontation.
He said his client only has one month left to serve in jail given the time he has already served.
