St. Louis County Police investigate a situation after an armed man entered an hospice building demanding drugs on Saturday, Aug. 9, 2014, in St. Louis County, Mo. Officer Brian Schellman says no one was hurt and said it "looks like a failed robbery attempt." Schellman says the man was armed with a handgun, walked into the de Greeff Hospice House and directed a nurse to take him to where the narcotics were. The nurse started walking with the man toward the back of the building, and then ran. Schellman says the armed man ran out of an unlocked door likely before police arrived.
