re the car and the sketch of the younger male if it comes to that are product of intellignce gathered LE didnt have details of these beforehand, someone offered up this information, someone under pressure and was either facing jail time or their partner/wife was and they did a deal.
Did one or more of the group arrive in the car, most likely, was it abandoned on purpose most likely... time will tell.
Was it a sexually motivated crime?.. No this wasnt a crime based on sexual pleasure at the press conference Doug Carter addresses the murderer and says this is all about 'POWER' to you! This crime was committed to publicly show the 'POWER' the murderer is able exert over someone. Wether that was power over the victim or power over someone connected to the victim is yet to be determind. My opinion is that this crime was videoed by the person/s involved and it was most likely videod using Libbys phone or a phone left at the scene.
Its not enough these days for criminals competing for status or revenge to verbally threaten or physically beat people up or shoot them outright, real power comes from fear, fear that reaches new depths of humiliation torture and suffering and showing this in real time. This visual impact leaves the deepest and most profound effect on the lives of people wether they know the victim or not.
The use of hard drugs have played a part in the acceleration of such crimes.
These are my opinions only
