EMERSON, Neb. (AP) — Northeastern Nebraska authorities have identified human remains found in rural Dakota County as those of a 41-year-old man.

The Dakota County Attorney’s office on Thursday identified the man as Kraig Kubik, of Emerson.

Authorities found parts of Kubik’s body at a trailer home near Emerson on Wednesday afternoon, and officials have determined that Kubik is dead. Officials have not said how they believed he died, but have begun a homicide investigation. Investigators continued Thursday to search for Kubik’s other remains.

Authorities say people are being questioned, but no one had been charged by Thursday afternoon.

Authorities say Kubik was last seen Tuesday night at his home. Investigators believe an altercation took place there, and he was forcibly taken from the residence.
