Do you have a criminal record, Leo?

Cooper, this old fool is obstructing a criminal investigation.

Two different kinds of twine.

Fibers of twine found in the railroad car.

I matched the sample from her wrist.

The same twine was used to bind the wrists of the Pulaski girl.

Conclusion, she was tied up twice, at different locations on the night of her death.

Once here, and once here.

Like this.

Sometimes my arms bend back.

Here we've got traces of pumice found in standing water outside the railroad car.

Soap.

Industrial strength.

I found identical particles in the back of Laura's neck.

It's not her home-use brand.

My conclusion, the killer washed his hands and then leaned in for a kiss, like this.

Good Lord.

Distinctive wounds found on Laura's neck and shoulder appear to be claw marks, bites of some kind.

An animal.

Look, it's trying to think.
