AUBURN, Wash. -- The spouses of two victims of cyanide-laced Extra Strength Excedrin capsules were asked to take polygraph tests by the FBI.
Paul Webking, whose wife Sue Snow died June 11, said he passed the lie detector test.
But Stella Nickell, widow of Bruce Nickell, declined the exam. Nickell died June 5 from ingesting the poisoned capsules.
'Her doctor and I told the FBI no because she's too shaken up,' said Bill Donais, Nickell's attorney.
'The police, the FBI haven't given me a moment's peace,' Webking said Thursday. 'They interviewed me daily. They interviewed the family daily.'
Webking married Snow, 40, an Auburn bank manager, late last year. She had two teenage daughters from a previous marriage.
Webking said that because he was questioned repeatedly by the FBI, 'I thought I was a primary suspect.'
'I took a lie detector test. It was a completedly negative one ... they told me that they were satisfied with my story, my answers.
'I understand they mound nothing derogatory in my history -- from talking to people -- to suggest I'm capable of something like this.'
FBI spokesman Joe Smith declined comment on the case, restating the agency's position that it does not comment on pending investigations.
'My gut feeling is they don't have enough to go on,' Webking said. 'If they solve it, it will be by accident, the person will accidentally trip himself up.'
