The circumstances are a tad different but the MO is very similar here to a case that is unsolved in Massachusetts , where as the death of a young woman employed by google was murdered while out for a jog the victim being (VM) - I know that assumptions are being made about VM's personal life which are leading many to believe that it was her involvement with certain activities that ended with her demise, but I think the circumstances with these two cases are too similar (body type, activity, how victim is found and most importantly the complete cluelessness of who a possible suspect could be as both girls seemed to be successful and no ties to anyone that LE would deem a viable suspect ultimately leading to some idea of a motive - there is no motive in both these cases, just random & unexpected) this is why I think we are looking for the same suspect here, one that clearly has a problem with girls who pay particular attention to their physical fitness, a suspect that is left to feel intimidated "lack of self worth" which would set this unsub in a rage, a rage that he would need to do whatever possible to take back control to get that feeling of self worth back - in every case that we study, or discuss with my students those cases involving sexual assault resulting in death (especially if the death is caused by asphyxiation - strangulation) its those cases we have found where the unsub felt most in control and got their sexual release through having total control over the life and death of their victim - in their mind bringing someone back to life over and over - this type of predator ultimately sees themselves as god, in my opinion. For predators that seek this type of power, they are ultimately the most dangerous. This power is almost as potent as heroin is to a narcotics addict - and once they have that hit, its not before long where that feeling of self worth is damaged. That said, it won't be too long in my professional opinion that these psychological deviants find another victim that will ultimately result in the finding of another body with the same set of circumstances. I hope I am wrong, but if I am not - I hope they catch the evil bastards that are doing this sooner rather than later!
