(CBS/AP)-- Police have identified Ahmed Dirir, a 59-year-old businessman, as the gunman who shot and killed three employees before turning the gun on himself after an argument at his small home health care business in St. Louis Thursday.
St. Louis police said in a late Thursday news release that 44-year-old Khadra Muse of Olivette; 29-year-old Seaeed Abdulla of St. Louis; and 54-year-old Bernice Solomon-Redd of East St. Louis were killed by Dirir in the shooting that afternoon at AK Home Health Care LLC just south of the downtown area.
St. Louis Police Capt. Michael Sack has said the gunman was the owner or co-owner of the nursing services provider, and that the victims were his employees.
Police said surveillance video showed the shooting began after a brief argument inside the office.
