Well, they connected the young guy with the AL shooting.
The gun in the car matched ballistically to the 11 sniper victims.
The car was rigged with a hole in the back for concealed shooting with a bi-pod and "sniper stand".
It looks like they got their man. Am I relieved.
A little Muhammad history I caught from CNN today (I was forced to watch it at the gym today...ugh...

)
He was in the National Guard (in LA?) and was given a dishonorable discharge for disobeying a direct order and striking a fellow NCO.
He joined the US Army and had a non-descript enlistment. No sniper training, but he was trained on an M-16 and scored expert (not uncommon and not anything like a sniper's training)
He converted to Islam and became Muhammad (his last name as Williams until this point)
Until this point, he seems to be happily married, but something happened and he became abusive and he and his wife split. She got custody of the boy.
He "kidnaps" the boy several months ago.
He goes on his shooting spree in MD (his ex-wife lives in MD)
He has no formal ties to Al Qaeda as far as can be seen thusfar, but he was sympathetic towards the 9/11 hijackers.
