SIOUX FALLS, S.D. (AP) — Sioux Falls police arrested one suspect but are looking for a second person in connection with a non-fatal stabbing. Authorities say 24-year-old Derek Jordan Arapahoe is charged with aggravated assault and resisting arrest. It's not clear if he has an attorney. Police say he swung a large knife during an argument at an apartment complex on Friday that struck a 21-year-old man in the head.
