Livingstone, Andrews and others in “Unfinished Business”

...Struck from behind, I thought.

[Frustrated with Livingstone's impatience] I do know a bit about skull fractures(!) A hammer, I'd say, with some force.

The cause of death?

Well, it didn't just give her a headache(!)

Why did O'Donnell go to all that trouble to prevent identification?

If she was attacked with a knife in the lay-by, the hammer blow to the skull suggests she was killed later.

Makes sense. He wouldn't use two weapons to attack her with.

[To Livingstone] That bails out your theory.

What's that?

That she was alive when she was taken back to Dalmally Road, like Cunningham said.
