No, KP was there. LE was there. A relative of CP (his mother?) was there.
Seth came straight from work after getting the message on his personal phone which he apparently leaves in his car while he works. He arrived before 8AM. There was a little chatter, he finished work, went to his car & saw the message, went back into work to make sure he was cleared to leave, went back to his car & went to C&K’s house. This was from his first Nancy Grace Show. The CP relative being at the house came out later, I don’t recall reading that from either of their Nancy Grace transcripts.
