Imagine you are a freshman in college...and you admire the killers at Columbine...but were too chicken to destroy the family in your hometown community...but you have an URGE to kill...so you take your urge with you to college and KILL strangers???
You are a loner at college...new in a dorm...no one really knows you..."still" feel like and outcast...you don't have friends, you can't make friends...you decide to punish the world.
Parents live in south Virginia...and they make you come home on the weekends...you are loney and follow parents request - Laundry gets done (get rid of trace evidence from clothes when shooting rifle) get more ammo...in a community that "may NOT be watching ammo sales too closely" - and of course - Parents don't have a clue...Sniper kid is home on weekends...doing his research on a family computer...plans all of his possible sniping areas.
Of course Freshmen college students in the dorm wouldn't "recognize" whether or NOT you are behaving "normally or NOT"! Other college kids are caught up in a lifestyle that is alien to him...and they alienate him.
Schizophrenia also "manifests" in the late teens early 20s...maybe he is schizophrenic...may be hearing voices...would also support the "college student losing his mind"...and college students who begin to lose their minds...act strange and people will avoid them...
ALL speculation...any theory is as good as any at this point AND until he is killed...BUT take into consideration...all of this SNIPING has started at the time traditionally FALL SEMESTER begins...
The two shootings heading SOUTH on 95 into Virginia on FRIDAY...verrrrrrry interesting......
