(AP) — A Northeast Nebraska man has been convicted of first-degree murder for killing his ex-girlfriend and her new husband last year.

Nebraska Attorney General Jon Bruning says 33-year-old Matthew Hinrichsen was convicted Monday of two counts of murder and two weapons charges. He is scheduled to be sentenced Jan. 28, and could receive two life sentences.

The jury convicted Hinrichsen in the December 2012 deaths of Victoria Lee and her husband, Alex Vargas.

Their bodies were found in a charred trailer in rural Antelope County, where the newlyweds were living. Prosecutors say Vargas died from three gunshot wounds, and Lee died of blunt force trauma to her head.

During the trial, Hinrichsen’s lawyers didn’t dispute that he killed the couple, but they argued the killings weren’t planned.
