chris heidt: there had been a methamphetamine lab. r having a methamphetamine lab there. murphy: chris said that before his father died, philip expressed concern that the man was getting out of prison. could philip and carey's deaths had had something to do with these country drug manufacturers? it was just as likely as the murders involving craig, the defense attorney argued. and, he said, it was just one of the many avenues pointing away from craig heidt that investigators chose not to go down. murphy: the defense attorney would argue in court that once the investigators learned about that affair between craig and robin, they decided that they had their man; when, in fact, the defense would say, that the true killer may have been someone involved with philip heidt's real estate dealings, a business sector that had taken a swan dive. joanne reiser took the stand for the defense. she was philip heidt's longtime professional assistant. and her testimony suggested that if philip didn't tell her something, then it probably didn't happen.
