Philadelphia man pleads guilty to stabbing neighbor to death over snoring

Robert Wallace was killed after breaking into Christopher Casey's home after becoming enraged over his loud snoring

A man from suburban Philadelphia stabbed his neighbor to death after the killer's loud snoring led the pair to argue violently, according to authorities.

Christopher Casey, 56, was recently handed a relatively short prison sentence after pleading guilty to involuntary manslaughter in the 14 January death of 62-year-old Robert Wallace. Casey also pleaded guilty to possessing an instrument of crime to close the book on a case with a motive that has not been too commonly seen in the US justice system.
