I'm mostly a lurker here, and I've tried hard to remain objective in terms of BM despite certain gut feelings. However, I am pretty certain he's responsible. Here is the most objective information that has brought me to this conclusion:
1. The sheriff
has said this is an open criminal investigation, so that rules out an accident, animal attack, or her leaving on her own accord. This leaves either a kidnapping or a murder with her body removed from the home. Because no description of Suzanne was released by the police to the media, this implies that the police have evidence that a kidnapping did not occur. This leaves murder with her body removed from the home as the only remaining option.
2. BM said in the video with TD that his name had been cleared. However, on July 9, LE said that they
had not formally ruled out anyone from suspicion.
3. The Morphew house has been searched twice, with sealed search warrants (which require a judge to agree with law enforcement that there is probable cause that evidence of criminal activity will be found) obtained for each search and evidence removed.
4. One of BM's job sites (where he was recently hired to lay dirt)
has been searched, which also was done using a search warrant.
5. BM says he has not been asked to take a polygraph exam. However, SM's family says
he has been asked twice to do so and has refused both times. I don't know why her family (who do not live nearby) would lie, and I don't think that LS (the reporter) would have stated this in her article if she had any doubts about the veracity of this statement.
6. In same
LS interview with a family member of SM, it was said that the data collected from BM's truck didn't match up. Again, I trust LS to only report this if she had confidence in its truth.
I'm probably forgetting some important things here. There is also PLENTY of less objective information that supports the idea that BM is behind SM's disappearance.
The other theories I've considered all have problems. For example, maybe it was a stranger who entered the house. This makes the bike staging hard to explain, as well as the perfect timing with BM and the girls gone. It could have been a friend of SM's or BM's or one of the girls who knew SM would be alone that day, but why then would they hide the body AND stage the bike?
I haven't yet heard a good theory that fits the few known facts of the case that really would absolve BM, but I'd love to hear one. IMOO.
