The detectives were still convinced Sandy was the killer.

The unknown male DNA hadn't shifted the suspicion from Sandy at all.

It had just added another layer of complexity.

Detectives had a whole timeline of how they imagined Sandy had carried out Leslie's murder.

Their theory was that on Tuesday, May 1st, 2001, after eating pasta for dinner, Leslie Prier had an unknown male guest over.

When Sandy got home, there was a confrontation during which the unknown male had been injured and left through the back door.

This would explain the unknown man's blood being found in those three locations and his DNA on Leslie's fingernails.

According to their official report, the detectives believed that Sandy had then turned his anger on Leslie, killing her in the foyer area and spending the early hours of Wednesday morning cleaning up before leaving for work as usual.

The report also speculated that the biggest wrinkle in Sandy's plan was Brett Reedy.

He didn't expect Brett to insist on coming over and see the blood that Sandy hadn't finished cleaning up.

This was all speculation based on key pieces of evidence that for Lauren didn't add up to the same result.

The pasta, for example.

All the time she ate in the morning.

Yeah, and she could have had it in the morning.

Like every day.

Yeah, so... So it wasn't on her to wake up.

If Leslie ate the pasta for breakfast, as Lauren said she often did, it was totally plausible she'd been killed on Wednesday morning.

And Lauren said they still hadn't found the person who left the mystery DNA in the house.

But don't you think that's really weird?

The detectives acknowledged that their theory wasn't perfect and that the mystery DNA had raised more questions than answers.
