GERING, Neb. (AP) — A district court judge has sentenced a Wyoming teenager to at least 60 years in prison for killing a western Nebraska jailer.

Sixteen-year-old Dylan Cardeilhac, of Torrington, Wyoming, was convicted in November of second-degree murder for strangling Scotts Bluff County jailer Amanda Baker in February 2014.

Judge Travis O’Gorman sentenced Cardeilhac on Thursday to 60 years to life in prison. He said that Cardeilhac’s criminal history and his lack of remorse demonstrated that the public needed protection from the teen.

Cardeilhac was sentenced in May to a maximum of 15 years in prison on separate charges of armed robbery and use of a weapon in a convenience store robbery.

His latest sentence on the murder conviction will be served consecutively to his sentence in the robbery case.
