An Arizona man has been sentenced to 30 years in prison for the stabbing deaths of a teenager and her grandmother on the Fort Apache Indian reservation.
Martyn Wallen pleaded guilty in July to two counts of second-degree murder.
He was sentenced late last month to 20 years on one charge and 30 years on the other. A federal judge ordered the sentences to run concurrently.
According to court documents, Wallen broke into a home to steal DVDs when he heard a cough and saw two females lying on a bed. He told investigators he grabbed a kitchen knife and repeatedly stabbed the grandmother. Her 15-year-old granddaughter had rolled on top of her to try to protect her.
Wallen was 17 at the time. He was tried as an adult.
