This case seems similar on spirit to Anne Le, the Yale murder victim. Loser guys feel unhappy in their own life and take it out on successful doctors. It is almost like they dislike the fact that a woman can be more accomplished than them and they take it out on the woman.
I wonder as women get more accomplished we will see more of this new category of murders -the jealousy murder.
Of course we do not know if this applies and what he knew about Melissa, whether she perhaps had her Dr. Coat on since she had meetings that morning. Etc. Although of course nothing can excuse murder, I doubt any argument could have been about a fee. I imagine it was more about her perhaps being educated on the needs of her home and her knowledge into "his" realm of things set him off. Made him feel "disrespectful."
Was it premeditated? Did he follow her before? Did he facebook her and look her up before he went? We do not know that. But if would see he looked her up online and followed her- he had to have because how else could he have followed her? and if he followed her, something HAD to have been brewing in his mind before, maybe sexual? could it have been that he saw her online, and during the visit he tried to make a move which she rebuffed and this is what he calls an "argument"?
Defense will say no bc penalty for snap decision will be less than premeditated. But it could have been premeditated rape and when she rebuffed he turned anger on her. again, similar to Yale case, where there too was an attempted rape.
Anyone who does this has to be EXTREMELY STUPID. If you murder someone during work it is very easy for police to find out you had a service call. He would be the number one suspect. That is one reason why I, as a single female, never feel that unsafe w a service person like cable, etc in my home. If they try anything, they would surely be caught and very swiftly so it would seem really stupid why someone would do that.
