A Wichita gun store’s business has doubled in the two weeks since a serial killer of the 1970s has reappeared, at least on paper, reports the New York Times. A man called himself the B.T.K. Strangler after the method of binding, torturing, and killing he used at least seven times. The killer first wrote a letter via a local newspaper in 1974 taking responibility for the strangling death of a family of four. He then killed at least three more times, breaking into victims’ homes, cutting their phone lines, tying them with distinctive knots and killing them slowly.
The cases never were solved. Now the killer has sent another letter to the newspaper, apparently taking responsibility for an unsolved 1986 murder. Now the city of 350,000, where police investigated 21 homicides in 2003 and cleared all of them, is fearful that a murderer it thought had disappeared is once again on the loose.
