Unknown Margaret Hart Killer- Texas- 1979

Ok the FBI has made a post about this case and found out several things about this case do to a El paso times article first off hart was born in El paso she was at point married to man Thomas James hewkin they divorced at some point she was last seen by her boyfriend going to a drugstore after leaving her apartment her boyfriend reported her missing his name was Brian Robinson he was 23 at the time and actually he was the one who verified her identity now this case is very strange she was at first early in the investigation El paso authorities thought there was a connection to the bandidos motorcycle gang however this was false she was strangled and was not clothed when she was found I think I have of couple ideas most killings like this are usually done by a opportunistic random psychopath and usually done with a bladed weapon or a firearm at least from what I have seen I think hart knew her killer this was up close and personal I mean who goes into a killing especially in a random patch of desert so another thing i believe is they had some knowledge of the area and given the proximity to fort Bliss I think harts killer may have been in the military possible also a el paso native who may have training on rough terrain makes sense i mean were not talking where most killings like this usually the perpetrators are like i said usually are opportunistic predators on this level i suspect it may have been a depraved monster but one who was very charismatic once again I'm just theorizing but I think it could be a viable theory
