A neighbor said Tamerlan Tsarnaev *also briefly exchanged his *urban look for religious dress, a long white robe, and beard. But he also said the transformation came as soon as it went: Tamerlan Tsarnaev shaved the beard about a month after he grew it.

bbm, I wonder when this occurred.
I don't have a link but somewhere it said that he shaved it about a month ago - take it with a grain of salt
