I think he may have been given a lie detector test regarding the whereabouts of his wife, e.g. "do you know where your wife is", "did you murder your wife" etc.
He obviously passed so was no longer a suspect. That was my take on it.

I think the OP means "how did he pass the lie detector test".
Some people can pass it as well as some people can fail it
There's a reason that lie detector tests can't be used as evidence anymore. It's because they are unreliable.
Lie detector tests only rely on how bodies react when a person lies. If your body doesn't react that way. The machine can't tell you're lying.
Or perhaps they just asked questions that he can sneak aroubd by telling half truths.
Above poster is right. Its the reason they are not admissible in court. They pretty much base them to being nervous. There have been people who didn't do anything wrong, but freaked out just because the science behind a lie detector test..then failed. So if you're a good manipulator, you can pass one of them...and still be lying!
