El Liquidore is one dumb *bleep*!
He lets the two idiot women go? With a bag of money? Based on their promises? What kind of ruthless drug dealers are these people? Did they pinkie-swear?
He should have demanded the book of coordinates. Keep Brenda while Teresa goes to get the book, with the promise of killing Brenda slowly and painfully unless Teresa comes back, alone, with the book, within an hour.
Then, he kills them both. Book problem solved. And he saves some money.
And Brenda is dead -- added bonus for the viewing public.
