SIOUX FALLS, S.D. (AP) — Family members of a man shot and killed by Sioux Falls police are questioning why officers did not use nonlethal measures in a confrontation with him. The brother and sister-in-law of the man who was killed have identified him as 52-year-old Elwood Dwyer. Police say he was shot by police after an hour-long stand-off Thursday when he exited a house armed with a knife and charged at officers. Dwyer was suspected of stabbing and wounding three people who were known to him, including two adults and a juvenile. Their conditions are not known. The Argus Leader reports police have not said whether other methods were used to subdue Dwyer before he was killed.
