JMO, TLM did far more than simply change her story a couple of times.
Prior to the abduction of VS, TLM wrote in letters and her journal of her desre to commit crimes, with many details exactly as they were committed in this case. A coincidence?
Through her lawyer, she stated her desire to help find the body and plead guilty to the crime to help the family. She then proceeded to lie to them during the Agreed Statement of Facts at her sentencing hearing. While she sobbed, whimpered and wept, she accused MR of killing VS...........and all the time knowing that she was the real killer and she was lying to a grieving family.
She allowed the family, LE, and the Crown believe that story, until Jan 2012 and then confessed to killing VS. Why the sudden sense of honour after all that time had passed? Maybe because she didn't know if LE had recovered the hammer or not, but she knew there would only be 1 set of fingerprints on it........and those would be hers?
I remember reading an article where her lawyer described how she and TLM wept together over the case. And yet, through all the tears, TLM didn't confess to killing VS. She allowed her lawyer to believe that MR did it. Was that a sign of true remorse?
After she was sent to jail...........TLM told a family member that it was unfortunate that a little girl was involved, but she had no real regrets and would do it again.
TLM is insane. She has no moral sense and is incapable of remorse. The only thing she cares about is her own survival, and she lies and manipulates to accomplish that goal.
She changed her story on who decided to buy the hammer.
Why did she think it necessary to buy a hammer and garbage bags?
After all this........people still want to believe parts of her story?
Other than her story, we don't know what they did at that location. Perhaps they all walked around the area for a bathroom break. We may get a better sense when the defense begins it version of events.
Knowing the surroundings doesn't make TLM any more trustworthy in my opinion.
