>> is there anything that adam has ever done in his life that would cause you to believe that he ever would have done the acts that he's accused of in this case? >> never anything. it's inconceivable. >> reporter: adam took the stand, too. >> did you hit rebecca on the head? >> i never hit rebecca on the head or anywhere else for that matter. >> then did you devise this scheme to cover up your wrongdoing by painting the saying on the door and making it look like she had been hanged by someone else? >> absolutely, positively not. >> reporter: the case went to the jury. >> did you feel confident as deliberations began? >> i felt we could possibly win very convincingly. >> reporter: less than four hours later, a verdict. >> i sat down next to mary, and i said, i'm sorry, this is probably not good news, the jury coming back this quick. it's probably going to be a defense verdict. we know we did our job, you didn't let rebecca die in vain.
