(AP) — Police in northeast Nebraska are investigating the death of a 51-year-old man as a homicide, but authorities aren’t releasing many details.

Steven Jorgensen was found dead in his home on Wednesday after failing to show up for work for three days.

Police say Jorgensen died as a result of a struggle inside his home, but they haven’t said how he died.

Eugene Jorgensen says his son’s death was a shock. He says his son liked his job as a machinist, but had trouble with people breaking into his home.

Steven Jorgensen was the victim of a Jan. 3 assault in which two Columbus women were charged.

Eugene Jorgensen says he wonders if his son’s death is connected to that January incident.
