What's the first thing you saw when you walked in?

Well, I think a better question would be what was the first thing that I smelled, and that was gasoline.

There was so much gasoline in the apartment, poured on the floor and on the carpet,

that as my partner and I would walk, it would kind of gush up next to our shoe.

The fire department was really concerned.

They said a spark could light this whole place up.

Why was it the building was not completely burnt to the ground?

Anybody can strike a match, but you got to know you got to have enough air.

With this amount of gasoline that was poured in the apartment, they didn't have enough air.

They should have left the door open to have vented it more, and we would have had a more complete fire.

So this was an arson, but not a very talented arson.

Exactly.

As investigators push deeper into the apartment, the kitchen reveals its own disturbing clue.

We couldn't find any of those knives, not in a drawer or maybe dirty in the sink.

They were missing from that house altogether.

We knew that could have been used as some sort of a weapon, so we certainly took note of that as well.

The missing knives raised the grim possibility that Holly was stabbed.

There were also signs of blood spatter in her bedroom, along with another disturbing piece of evidence.

Then eagle-eyed detectives spot something easy to miss, a single bullet hole in the closet door.

Amid the devastation, one piece of evidence survived, and it would become the investigation's biggest clue.
