This is true, but the forum would not allow me to post the link.
The sad thing about this is not only a vicious murder, but the fact that a 19 year old Marine was obviously overlooked by his authorities for having aggression issues. I found nothing stating whether or not he was in combat, but PTSD would surely explain something like this. His youth may have put him in denial that he even had a problem. We train our service members to kill, send them into combat, then do not give them the necessary tools to assist them to assimilate back into society. Keep in mind he picked up a woman in a bar, took her to a motel for sex, then found out the "she" was biologically a "he". This may have been seen as a mark against his masculinity, and he needed to "prove" he was a man. Everyday, military men must be "men" and use their testosterone in training and combat, then we are surprised and we are shocked they kill. Not all of them can handle this type of life--especially at 19 years old, he isn't even old enough to drink in the US.
My heart goes out to both families, and I hope this does not tarnish the outstanding servicemembers who protect us day and night. Who give their all for our safety.
