SIDNEY, Neb. (AP) — A 54-year-old man has been sentenced to life in prison in the killing of a 30-year-old Sidney woman.

Larry Martinez was also sentenced Wednesday to 10 to 50 years in prison for using a firearm to commit a felony. He had been found guilty of first-degree murder in the July 2012 death of Mandy Kershman.

According to prosecutors, Martinez became angry about a text message Kershman sent him. Authorities say the victim was at a friend’s house and Martinez went to the home to confront Kershman about the message and shot her. According to prosecutors, Kershman and Martinez had been in a relationship at the time of the shooting.

Sentencing in the trial had been previously delayed so the judge could determine if Martinez was competent.

Martinez’s sentences will run consecutively.
