A cached profile photo that matches his picture, and tweets from other users he's interacted with suggest that this is the twitter account of 19-year-old Dzhokhar A. Tsarnaev, the fugitive suspect #2 in the Boston Marathon bombings: @J_tsar. The account is listed under the name "Jahar," which is what classmates called him because his full name was hard to pronounce.

Surprisingly, Tsarnaev has been active on Twitter since the bombing. His last tweet was on Wednesday, two days after he is alleged to have helped carry out the Marathon bombing:

I'm a stress free kind of guy — Jahar (@J_tsar) April 17, 2013

The day of the bombing itself, Tsarnaev tweeted:

Ain't no love in the heart of the city, stay safe people — Jahar (@J_tsar) 16 de abril de 2013

("Ain't no love in the heart of the city" is a Jay-Z lyric)

Last year he tweeted:

so much hate i need a ak — Jahar (@J_tsar) July 15, 2012

(Update: This is a lyric from a Kanye West song.)

But there is not much on the account that suggests the user of the account was be anything but a normal 19-year-old kid.

He tweeted about Chechnya, where he was born (his family moved to the U.S. in 2002):

i hold my own i got that #chechnyanpower — Jahar (@J_tsar) March 14, 2012

a decade in america already, i want out — Jahar (@J_tsar) March 14, 2012

proud to be from #chechnya — Jahar (@J_tsar) April 29, 2012

i hold my own i got that #chechnyanpower — Jahar (@J_tsar) March 14, 2012

He tweeted about music:

ooh baby i love your way, everyday. — Jahar (@J_tsar) April 29, 2012

you've been hit by a smooth criminal — Jahar (@J_tsar) May 5, 2012

maybe im amazed at the way you love me all the time — Jahar (@J_tsar) April 10, 2012

and random stuff:

i didn't become a lifeguard to just chill and get paid, i do it for the people, saving lives brings me joy #lifeguardoftheyear — Jahar (@J_tsar) May 29, 2012

having your own car is sooo #clutch — Jahar (@J_tsar) February 13, 2012

drugs are a crutch for people who cant handle reality — Jahar (@J_tsar) March 14, 2012

He was also apparently a 9/11 truther:

Idk why it's hard for many of you to accept that 9/11 was an inside job, I mean I guess fuck the facts y'all are some real #patriots #gethip — Jahar (@J_tsar) September 2, 2012

On twitter, friends he interacted with are expressing shock that he's a suspect.

I can't believe this jizz was a cool cat at my crib daily- this shit is to wild for me- guess you really don't kno niggas nowadays — Trippin No L' 4/20 (@NickkeyG) April 19, 2013

The jahar I knew was a real nigga — Trippin No L' 4/20 (@NickkeyG) April 19, 2013

Anyone who believes this BULLLSHITT about Jahar is Fuckinnnnn cooked. He's the last dude to be harming anyone or anything — EL PLAGA™ (@Kid_Wavyy) April 19, 2013

Especially given his, um, laid-back reputation:

I never would have thought that someone that smoked as much weed as Jahar would be on the News for terrorism. — mac (@ChinksMcGee) April 19, 2013

And his friends are now experiencing the inevitable wave of reporters and online gawkers now that the twitter account has been discovered:

My mentions going crazy because of these bloggers, journalists, and twitter reported. I'm tight. — mac (@ChinksMcGee) April 19, 2013

Update: BuzzFeed confirms with a high school classmate of Tsarnaev that this is his twitter account.
