SIOUX CITY, Iowa (AP) — Investigators suspect drug trafficking is related to the fatal shooting of a man in Sioux City. Police say 26-year-old Javier Cheron died at a hospital Wednesday evening. Police say he was armed when he arrived there.

No arrests have been reported in Cheron’s slaying, but a search of the home where police think Cheron was shot turned up stolen handguns and illegal drugs. Police subsequently arrested 60-year-old Liborio Martinez-Rubio on drug and weapons charges. Authorities say Cheron’s death was the first Sioux City homicide of the year.
