First and foremost, it details the prize paid for Slobbertooth's whole family to be dead and make it look like a hate crime:

Frigg added a note that she made the connection too and uncovered this way that Eliza Thorin was most likely the instigator of those contracts, since her husband was at the time out of contact and actually didn't participate in any business activities.
She further speculates that the murders were most likely meant to keep a secret from getting out. She notes that Wayfarer Inc. - the buyers of the factory - would probably be interested to learn about that secret, since there would be no other reason to kill ex-employees about it otherwise.
