Dzhokhar Tsarnaev Twitter Account

His old account, almost certainly him.

Last message was from a Muslim Imam.

Attitude can take away your beauty no matter how good looking you are or it could enhance your beauty, making you adorable.

Here's his account.

From the day after the bombing:

Ain't no love in the heart of the city, stay safe people

And later this:

There are people that know the truth but stay silent & there are people that speak the truth but we don't hear them cuz they're the minority
