They include statements about Islam, observations on pop culture, a boast about beer pong, and trash talk about women.
A MONDAY message on Twitter - "stay safe people" - seemed aimed at soothing Bostonians rattled by deadly terror attacks earlier in the day. But that entreaty was apparently sent by the prime bombing suspect.With the city of Boston on lockdown for most of Friday and suspect Dzhokhar Tsarnaev still on the loose, attention has focused on the 19-year-old's social media accounts for clues about his life and his potential motivation for apparently setting bombs that killed three people and wounded more than 180.
The focus has zeroed in on the still-active Twitter account @J_tsar, which one of his Twitter friends confirmed to AFP as belonging to Dzhokhar.
"Ain't no love in the heart of the city, stay safe people," he tweeted at 8.04pm local time on Monday, just hours after Boston was rocked by twin explosions which police say he set with his older brother Tamerlan, who was killed on Friday in a shootout with police.
A tweet one week prior to the blasts may have offered cryptic hints at what was to come: "If you have the knowledge and the inspiration all that's left is to take action," @J_tsar tweeted on April 8.
Twitter said as a policy it does not confirm the identity of users, but there seemed little doubt on Friday that @J_tsar, with the handle "Jahar," was in fact Tsarnaev.
"Tat my name on you girl so i know it's real oh and make sure to spell it right, its spelled Dzhokhar," he posted last May 5.
His followers, just a few thousand by early Friday, soared to more than 58,000 in the hours after he was named a prime suspect.
His Twitter page is adorned with the emblem of the FC Anzhi Makhachkala soccer team, in the southern Russian region of Dagestan where, according to his uncle who spoke to reporters, Dzhokhar was born.
A perusal of the 1099 tweets posted by @J_tsar portray an everyday kid with a wide variety of interests: sports, hip-hop lyrics, girls, Islam, TV shows like Breaking Bad, and cars.
Some friends who say they went to high school with him have posted their disbelief at how a classmate could be responsible for the worst terror attack on US soil since the September 11, 2001 suicide plane strikes.
"Yeah he went to rindge, he graduated with me and we had a few classes together," wrote a longtime Twitter friend "Samantha" on Friday, referring to their time at Cambridge Rindge and Latin School, in Massachusetts. Dzhokhar had exchanged tweets with Samantha as far back as November 2011.
One message from August 2012, a response to a user who has since locked his tweets and made them unviewable, provides a jolt to those scrolling through Dzhokhar's account.
"Boston marathon isn't a good place to smoke tho," he wrote.
The final message on his account is a Wednesday retweet of a comment by Mufti Ismail Menk of Zimbabwe.
Afterward Menk condemned the Boston attacks on his own Twitter feed, saying "the perpetrators must face justice."
One of Dzhokhar's post-bombing tweets was a hair-raising response to a fellow Twitter user.
"What 'god hates dead people?' Or victims of tragedies? Lol those people are cooked," Dzhokhar wrote.
