when i was in college i met a 14 year old girl who invited me to her house when nobody else was there to have sex. after a while she introduced me to her girl friends, also 14, who also wanted to have sex with a college boy. until i graduated and left town, i thought i was in heaven. of course, looking back, i know it was illegal. if i had been caught i would have been sex offender. but since then, i have never touched an underage girl and am happily married and a good father.
i don't know the circumstances of the person who moved in, and i ain't saying that all sex offenders are good, but unless you know the whole story, you don't know the whole story. should you be concerned? yes. but i wouldn't kill the guy without knowing more. people change. :2 cents:
