It looks like he replied to a comment on his FB page just 5 hours ago.The comment and his reply are listed under a post dated December 1st (the one about fake people being blessed):
"You apparently do not know me at all because if you did you wouldn't be making retarded [expletive] comments but I'll say this one time and one time only I am ready to die to protect the things that I love. So if you fake want to be gangster [expletive] are ready to die for your beliefs please commence to talking [expletive] and shoot on sight! Things are not always what they seem but far be it for me to explain myself any thing that I consider beneath me. I'd suggest you find a [expletive] Hobby because I'm so far out of your [expletive] leave you can't even see this high I'm sure you probably have a nice life with a lot to lose think about that the next time you run your [expletive] mouth to a real gangster!"

This is actually somewhat good news because LE should be able to track them down fairly quickly if they've been monitoring his online activity. A warrant demanding information about location activity should be served to FB rather quickly. This information should reveal LJ's location at the time he replied, at the very least.
He clearly couldn't control himself long enough to stay off social media, but I wonder why be responded to that particular comment but nothing else.
