False.
They did do a polygraph. And they passed with flying colors. They refused to do one for the police because the police were convinced they were guilty.

Oh? And who administered the polygraph and where and when did this exam take place???

The police were doing their jobs - trying to clear them. They obstructed the paths to that goal.
