"Deputy Sheriff Halpin and Agent Charles Bintliff, of the United States Treasury Department, were shot and killed near Redfield, South Dakota, while attempting to arrest a man who had wounded another federal agent one week earlier. Deputy Sheriff Halpin and Agent Bintliff were with two other officers and they arrived at the man's farm at 0130 hours. The officers separated and Deputy Halpin and Agent Bintliff went to search the barn. As the two searched the barn, the man opened fire on them with a shotgun, striking Agent Bintliff in the chest and Deputy Halpin in the abdomen. Both men were killed instantly. The suspect fled but committed suicide."
