I've been lurking here for a while but wanted to sign up to share my thoughts. I agree with most of the posts that this was most likely a case of extreme and out of control jealousy from TM. I have to wonder if SM has a history of cheating or if HE was the first to respond to his advances. He seems so ordinary, I don't think anyone his age would see anything special in him, but I can see a younger person fall for his act. If SM has cheated before, what made HE so different that she should suffer such violent revenge? Was it the first time SM got caught? Pregnancy? Was she the youngest or prettiest? In searching through TM numerous internet posts - I actually think she had an internet addiction - I found an old picture of her that is creepy in it's similarity to the TK uniform. I wonder if HE reminded her of everything she was not and that came crashing down on the fantasy life that she created for herself. I think however she found out about HE, there was an obsessive need to know every detail of what happened between SM and HE. I doubt SM was truthful, the business card excuse was to take the responsibility off of him, three times in her backseat was a good number to throw out there - probably after insisting nothing happened until he broke down or was found out. I believe all of it was very calculated after that. TM probably stalked HE online and her jealousy grew into a huge, insatiable monster. And HE, in way over her head, paid the price.
