So she was murdered in that hotel.

The autopsy revealed she had been strangled.

We flipped the switch then and it went to a homicide investigation.

A couple days later, we get a letter through the mail from a person purporting to be somebody who is reenacting the Zodiac murders from the West Coast.

From 1968 to 1974, several newspapers in the San Francisco area received a series of anonymous letters from the self-proclaimed Zodiac killer who claimed credit for up to 37 murders.

The 2007 movie Zodiac put one of America's biggest unsolved murder cases on the big screen.

It's unsigned except for a symbol.

A letter has surfaced claiming the murder is a work of a serial killer.

Good morning, Robin.

That letter certainly has gotten everyone's attention.

The Fayetteville Observer received a letter, and this is what the letter said.

We were sitting down in a meeting with CID about this exact letter when we got the call to go out to Holly's apartment.

We were like, what is going on here?

It's like something you see in a movie.

The guy's trying to communicate with the police by way of mail.

And you're looking at the possibility this could be the same killer.

Of course, the same symbol is on the bottom of this letter that was written on the mirror in the hotel room in the lipstick.

So are we dealing with a copycat here?

We very much thought that it was a possibility these were connected.

Was Holly this killer's next victim, which would have been just a couple of weeks after Megan Tuma's murder?
