It's not much of a stretch to think the 9/11 anniversary played a significant role in the Tsarnaev brothers antisemetic jihad wet dreams.

Also note . . .
Christopher Medeiros of Arlington and his roommate, Elizabeth Jason, said yesterday [9/15/2011] by phone that they were longtime friends of Mess. They said he told them Friday about a violent altercation he had the week before with his girlfriend. They said that, according to Mess, his girlfriend threw knives and beer bottles at him after he refused to talk with guests that she had brought to the apartment.link
Although we do not know the identity of Mess's knife-throwing girlfriend, we do know that one of the Tzarnaev sister's residences (West New York, NJ) was raided by the FBI).
No doubt in my mind he killed them
I’m only speculating, but the mary jane tossed on their bodies, combined with the little brother being a pothead, aligned with the reality that the older brother had become a religious zealot, leads me to believe the older brother killed the people in a moose slime ritual of honr killing for hooking his brother on pot. Yes, it’s demonic, but that’s what Is Slime leads humans into.
