CONCORD, N.H. — A man sentenced to 20 to 40 years in prison for his role in a home invasion that left a mother dead and her 11-year-old daughter maimed was granted parole Thursday on one of his convictions but still faces at least a decade more behind bars. Quinn Glover pleaded guilty to burglary, robbery and conspiracy in the 2009 Mont Vernon attacks. Glover, who was then 17, and three others broke into a house and found Kimberly and Jaimie Cates asleep. Glover testified against two co-defendants who hacked and slashed the victims with a machete and a knife, killing 42-year-old Kimberly Cates and severely injuring Jaimie, who lost a portion of her foot in the attack. Steven Spader and Christopher Gribble are serving life sentences.
