Prosecutor David Fornshell

We know there's some more that happened than what you shared the other day.

So she was under the belief that the baby had been set on fire.

I was surprised.

There's some evidence to show that there was some burning on her.

No, and I did nothing with fires.

Yes, because they had told us certainly.

With scientific certainty, there was the fire.

Tell me everything that you were thinking and everything you did.

Did you hear anything like little gurgle sounds?

How did you know at first, you know, that she was probably alive just a little bit?

That word, yes.

I said that word first.

I tried to clean up the baby just a little.

Brooke Richardson is in the Warren County Jail tonight.

We know a lot more tonight about the Carlisle teen mom now accused of the horrific crime of killing her newborn and then burning the baby's body.

She gently laid the baby down in the ground.

She didn't have a casket.

I'm literally speechless with how happy I am

My belly is back, OMG, and I'm never, ever, ever, ever letting it get like this again.

Those are the words that Brooke Richardson texted to her mother just hours after she murdered her infant daughter in the middle of the night and buried her lifeless body in the dirt behind their home.
