NORTH PLATTE, Neb. (AP) – A 24-year-old man has been charged with manslaughter in the fatal stabbing of another North Platte man. Nathaniel Polanco also was charged with use of a weapon in the slaying of 24-year-old Michael Fernau. Polanco appeared in court on Monday and is due back on Thursday. Officers sent to a North Platte home early Saturday morning found the injured Fernau. He died later at Great Plains Regional Medical Center. Police say it appears Fernau and Polanco were arguing just before the stabbing. Authorities believe alcohol was a factor. Polanco remains jailed, pending $500,000 bail. Court records don’t yet list the name of his attorney.
