Did it seem to indicate that this may have been done by somebody who knew the details of that apartment?

Holly either let that person in or that person made his way into the apartment by some other means, possibly by a key.

Detectives believe that whoever was in Holly's apartment also tried to cover up evidence of what happened there.

We found actually a carpet cleaner and we tested that carpet cleaner and it tested positive for blood on a preliminary test.

Just from what I'd seen, the reaction we got from the luminol, the amount of carpet that was cut from the floor in the bedroom, the bed sheets and clothing and stuff had been taken off the bed.

All those were indicators for me that there had been at least some measure of crime scene cleanup that had tried to take place.

Whoever did this might have tried to cover their tracks, but that crumpled letter was left behind.

It appeared that whoever wrote that note was inside the apartment when this terrible thing happened to Holly, but it does not identify who they were or what their relationship to Holly was.

The person that wrote this letter is the person that tried to burn that apartment, which is the person that knows where Holly's at.

That's the way I was looking at it.

At the time of Holly's disappearance, we knew she was going through a tumultuous time in her life.

As investigators look into Holly's personal life for clues, they learn that about eight months before she went missing, Holly had filed a request for a temporary restraining order against an ex-girlfriend of her husband named Lindsay.

In the filing, Holly alleges that for 18 months, the defendant has continuously posted pictures of herself and my spouse on the internet with comments directed at me and claims I have changed my phone number six times.

Lindsey denied harassing Holly.

In fact, she tells investigators Holly was the one harassing her.

And she was never served with Holly's request for a restraining order.

She was considered a threat.

That's why we wanted to look at her, because we had to consider her.

But when investigators talk to her, she denies having anything to do with Holly's disappearance.

They also discover she had an alibi on the date Holly disappeared.
