A northeast Nebraska man accused of killing his ex-girlfriend and her new husband has pleaded not guilty.

The pleas were entered on Wednesday for 33-year-old Matthew Hinrichsen in Antelope County District Court.

Hinrichsen has been charged with arson, two weapons counts and two counts of first-degree murder in the deaths of 25-year old Victoria Lee and her husband, 30-year-old Alex Vargas.

Investigators found the couple’s bodies on Dec 8 in a burned-out mobile home near Ewing. Authorities say the couple were shot before the mobile home was set on fire.
