Just hours after the Boston Marathon bombings, one of the brothers accused of staging the attack urged his followers on Twitter to "stay safe people".
As the authorities hunted Dzhokhar Tsarnaev, attention focused on the 19-year-old's social media accounts for clues about his potential motivation for allegedly setting bombs that killed three people and wounded more than 180.
Dzhokhar Tsarnaev was captured in the Boston suburb of Watertown , less than 24 hours after his 26-year-old brother and alleged accomplice Tamerlan was killed in a shoot-out with police.
Friends of Dzhokhar confirmed he was an active Twitter user, tweeting under the handle @ J_tsar .
"Ain't no love in the heart of the city, stay safe people," he tweeted at 8:04pm on Monday, just hours after Boston was rocked by twin explosions that police say he set with his brother.
It was one of a dozen messages he posted on Twitter in the hours and days after the tragedy.
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.
"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 on May 5.
His followers soared to more than 75,000 in the hours after he was named a prime suspect.
A perusal of the 1,099 tweets posted by @J_tsar portray an everyday kid with a wide variety of interests: sports, hip-hop lyrics, girls, Islam, cars and TV shows like Breaking Bad.
His Twitter page is adorned with the emblem of the FC Anzhi Makhachkala football team, in the southern Russian region of Dagestan where, according to his uncle, Dzhokhar was born.
But in one of the 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," @J_tsar wrote.
The final message on his account is a retweet on Wednesday of a comment by Mufti Ismail Menk of Zimbabwe.
Menk later condemned the Boston attacks on his own Twitter feed, saying "the perpetrators must face justice".
