They were going to have a big slumber party, a big sleepover.

It's Friday night.

They're wanting to get out of there.

The girls were all picking up, cleaning up the yogurt store.

Something horrific and evil was about to walk in that door.

It all started late one Friday night with a police radio call to Detective John Jones.

An Austin police homicide investigator happens to have a news crew riding with him in the car that night, and he gets a call and starts speeding to the scene.

The case that would become known as the Yogurt Shop Murders begins on a December night in 1991 in Austin, Texas.

There was a police officer and he was just patrolling the neighborhood and he noticed smoke coming out from one of the doors and it turned out to be the yogurt shop.

So he pulled in to investigate and immediately called for fire officials to respond to the scene.

Fire suppression efforts were aimed towards trying to put out this fire.

And while doing so, they happen to trip over a body.

And that is when they discover a horrific scene.

Then they recognize it's two, and then three, and then finally four.

The yogurt shop, it's probably like a typical retail space in a strip mall.

You have the consumer area up front, tables and chairs, and there's a counter kind of in the middle, and then there's the back room where the storage and office and everything is.

I got there right after the fire had been knocked down.

Very smoky.

There was water dripping from the ceiling.

It was overwhelming.
