Lots of broad strokes being brushed, here, about teenage boys and people who are quiet and don't lose their temper....
Not all 17 yr. old boys have such "raging" hormones that all they think about is sex.....an image was that was opined here. How about teenage girls? Raging hormones? Thinking about nothing but sex? What age does it start? 12-13-14?
Quiet people without explosive tempers don't ALL become abusers/murderers or commit suicide or have heart attacks/strokes. Some people are just not loud and boisterous and outgoing. Some people have an even keel...no temper tantrums or acting out or "losing it"....some have both. Quiet, even tempered. No pent up rage....
We don't really know where GG fits in these descriptions. He's been described as quiet. Except on the wrestling mat. I've read about him being described as nice. Pretty nondescript. One neighbor says she warned him away from her 11 yr. old daughter....but, not why she did. The victims family seem to have believed he was not threatening....enough to be considered part of the family....I'm sure more will come to light as the case moves forward. I hope so.
