There were two more pieces of the puzzle that detectives thought looked bad for Sandy.

The first, phone records.

Back in 2001, call records were harder to verify, so investigators couldn't confirm that 9 a.m.

call Sandy said Leslie had made to him about the toilet paper.

And then there was the polygraph.

In the days after Leslie's death, Sandy cooperated with everything the police asked of him.

He gave them access to his work computer and his phone.

He allowed them to take photographs of small cuts on his body, and he volunteered to take a polygraph test.

Perhaps he thought it would help with the suspicions growing around him, but it didn't because Sandy failed.

Investigators told me that failing a polygraph test by itself might not have meant much.

Polygraphs are, after all, notoriously unreliable.

But taken with all the other odd details from Sandy's interactions with police, his position as number one suspect was assured.

It wasn't just the detectives.
