Bailey thought maybe it was true, but all the evidence showed it was false.
I was sure it was true.  I was absolutely sure they killed them! Why did you think that?  Why would they kill them? Well, everyone knows they were messing around with their wife... Yeah, but when they died they were on tour in Europe and them and their wife were split up and they were already involved with that Russian supermodel. Yeah but they were killed with their gun! Yeah but the robber confessed that they found the gun in a drawer while they were robbing the place!
