KANSAS CITY, Mo. (AP) — Police and the FBI are investigating whether an argument over an online game prompted a hoax call that led to a house where an officer shot and killed a Kansas man who apparently wasn't involved in the dispute. Wichita Deputy Police Chief Troy Livingston on Friday blamed a "prankster" who called 911 and made up a story about a shooting and kidnapping. He did not mention reports that an argument over online gaming was at the heart of the prank, although he said investigators had made good progress tracking online leads.
