BTK Suspect Tracked Thru Communications Sent About Crimes
Rader, 59, was arrested last week.
The pastor of the church where Rader was president of the church council told The New York Times it was a computer disc from the church's computer that led police to Rader. Police did not confirm that, however.
The messages began shortly after the first killing but stopped in 1979. They began to appear again last March. The latest one, in the form of a manila envelope containing several items including a computer disc, was sent to a television station Feb. 16.
The Times reported the disc was traced to a computer at the church and the pastor said Rader had recently used the machine.
