Can you direct me to the library?
Well, I listened to the 911 audio. Guy is guilty as heck, IMO. He was nonchalant but repeated their "theory" a few times, about how the fire was a likely diversion so "they" could steal his kid, who had been mistaken (yeah, in their small house, right?), for the boss' daughter.
Look, no one who discovers their kid missing is going to put all that together so quickly. They are going to be feeling white hot panic at that moment. But not Adam. He was so calm and remembered to repeat their "theory" on a few occasions. He also joked about his child who they never see who is now missing and he thinks abducted by bad guys? And he can joke and giggle? B.S. This guy is at the least, an accessory. He knows his child is dead and his only concern is for his wife and his own freedom. Sickening.
