US: A 31-year hunt for a sadistic serial killer known as 'BTK' appeared to have ended in Kansas at the weekend with the arrest of a man who was turned in by his daughter.
Dennis Rader (59) a married father of two and a former church leader, was arrested in Wichita, Kansas, in connection with at least 10 murders dating back to 1974.
'BTK', a self-coined nickname for 'Bind, Torture, Kill', sent rambling letters to the media.
In one, he asked: "How many do I have to kill before I get my name in the paper or some national attention?"
Mr Rader was arrested after his daughter, Kerri (26) reported her fears that her father might be the killer. Police asked her for a voluntary blood sample. They found it was a 90 per cent match with "BTK".
Police say they plan to file 10 counts against Mr Rader in connection with killings between 1974 and 1991, eight of first-degree murder and two other homicide charges.
"BTK" first gained notoriety in the mid-1970s with seven murders in five years.
His first victims were a 38-year-old retired air force mechanic, his wife and two of their children, who were murdered in their home.
While his victims appeared to be chosen at random, his method of murder was consistent. He would cut telephone lines, break into homes, tie up his victims and force them to suffer a slow death.
