Boston bombing suspect Dzhokar Tsarnaev has tweeted since the Boston Marathon bombings on what two friends of his tell CNN is his Twitter account.
His tweets included one at 1:43 a.m. Wednesday that said, "I'm a stress free kind of guy."
On Monday at 8:04 p.m. -- hours after the bombings -- he tweeted a quote from rapper Jay-Z, "Ain't no love in the heart of the city, stay safe people."
On Tuesday shortly after midnight he tweeted, "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."
Tsarnaev does not describe himself in his Twitter profile, which reads only, "Salam aleikum."
The most recent tweet is one he retweeted on Wednesday from Mufti Ismail Menk, who identifies himself as a Muslim scholar. "Attitude can take away your beauty no matter how good looking you are or it could enhance your beauty, making you adorable," the tweet reads.
Another tweet from Tsarnaev on Tuesday was a quote from rapper Eminem: "Nowadays everybody wanna talk like they got somethin to say but nothin comes out when they move their lips; just a bunch of gibberish."
After another Twitter account posted a photo Tuesday saying it showed a man who was going to propose to his girlfriend at the marathon in Boston and found her dead, Tsarnaev tweeted a two-word response: "fake story."
Another of Tsarnaev's tweets from Tuesday reads, "So then I says to him, I says, relax bro my beard is not loaded." On Friday, another Twitter user retweeted that message, and added the words, "But my backpack is."
