"Here's the deal, kid," says Laine. "We've got a full-blown murder on our hands. Double homicide…single…equicide. Now I don't know who did this, but I'll be damned if I don't find the perp. You want to help? Go talk to those bums over there." He motions towards the nearby farm, where you can see several hobos wandering around. "They've been up to nothing good since Stormwind City's Park blew up and left them nothing better to do than...that."
Talk to the bums. Decide not to take Laine's advice after all and look for clues on your own.
