mother did not kill nicholas. accidently, on purpose, whatever frederick said, it never happened. >> when we first got my dog, he was always digging in the back corner over there with the tree is, and one day i was mowing and saw pieces of plastic, kind of like a tarp material sticking out of the ground. i tried to pull it up to get it out and it kept ripping on me. so i never paid any attention to it and never gave it any thought until last night when we were speaking on the phone. >> and the bush has been there a while. >> i had initially tried to get ahold of jason prior to frederick's arrest and couldn't. and then when i finally did get ahold of him, i asked him about the disappearance of his brother. he just seemed totally apathetic about the disappearance of his younger brother.
