Gonna have to say it makes the most sense - the older brother was likely the more radicalized one, the younger one under his influence. At least, that will be the story tomorrow morning when defense lawyers start their battle. They'll say it was actually the older one who planted the bombs, that this was just a scared kid, look at the evidence of him running over his brother trying to flee away...
Really wish the world had a fast forward button, as I'd very much like to swap to 2016 right now.
I think the DC area sniper duo could be a similar pattern of older and younger.
But wasn’t the younger brother the one captured on video placing the bomb that killed the 8-year-old?
If so, whether the older bro was the ringleader or not will be a moot point.
