Christopher Casey, 56, was sentenced to 11½ to 23 months in county jail for the involuntary manslaughter of his neighbor, Robert Wallace, 62, after a dispute over Casey's loud snoring escalated into violence. The men had a history of altercations lasting over 18 months, which came to a head when Wallace threatened to kill Casey and physically confronted him, leading Casey to stab Wallace multiple times with a military-style knife. Casey claimed he acted in self-defense due to fear of Wallace, who had bullied him and made repeated threats. Despite pleading guilty to manslaughter, Casey's defense argued he was a victim of sustained abuse. The case highlights the tragic outcomes of neighbor disputes and the complexities surrounding self-defense claims. Casey will also serve three years of probation following his jail term.
