You can see how Sandy's reactions to what was happening around him might have looked odd to investigators.

Remember, right after Sandy had first seen the blood in the foyer and the officers had arrived at the house to investigate, Sandy had made a joke.

You mean business, he'd said.

And now, in a police interview about his wife's death, Sandy was volunteering descriptions of heated arguments he'd had with Leslie, some in the weeks before her death.

And at this point, Leslie's death had not been formally announced as a homicide.

48 hours out, the official language was that the case was being treated as suspicious.

But it's hard to believe that Sandy didn't realize how his description of his marriage must have looked to investigators.

If detectives thought these revelations about the Prier's relationship were surprising, they hid it well and kept on moving through the timeline of events.

They zeroed in on the morning of Wednesday, May 2nd, the most important window for the investigation.

Sandy said it was just like any other day.

Sandy was just as detailed about Wednesday morning as he had been about Tuesday evening.

He said that after he showered, he left for work.

It was around 7.35 a.m.

He remembered specifically because he had a board meeting that day and wanted to be there early.

He got to his office at around 7.50.

At 9 a.m., he said his secretary put a call from Leslie through to his office phone.

In Sandy's telling, this conversation about toilet paper was the last conversation of their 27-year marriage.

At around 11.30 that morning, Leslie's boss, Brett Reedy, called him to say she hadn't shown up at work.

And an hour after that, Sandy described standing outside the house waiting for police to finish their search.

In his hour and a half interview with the detectives, Sandy broke down twice.
