"Looks like we got ourselves a real 'whodunit' here, rookie," says Laine. "It looks like the locals aren't willing to talk, and the clues we got are damn near worthless, so we're going to have to initiate plan B...Be on the lookout for Two-Shoed Lou. He's an old confidential informant of mine who makes his home at the farm to the west. Head there and find out what he knows. If he gives you any guff, tell him that Horatio sent you."
Go find Lou and talk to him. Check for clues in the area. You can do better than this. Go to this Alpert at Moonbrook and see if he really does know anything about this.
