A New Hampshire man has been sentenced to 40 years to life in prison

A New Hampshire man has been sentenced to 40 years to life in prison for fatally stabbing his mother after the two had argued about the volume on the video games he was playing. Thomas Humphrey, 47, was sentenced Tuesday after pleading guilty to second-degree murder and arson in the November death of Linda Tufts, 70, inside their Goffstown home. A prosecutor said Humphrey, who lived in the basement, stabbed Tufts multiple times and then lit her body on fire. The prosecutor said the two had recently argued about how loud he was playing video games on the PlayStation she had just given him for his birthday. Humphrey was found at the bottom of the basement stairs with self-inflicted wounds, holding a knife.
