Body may have been found of young missing student named during massive Boston manhunt.
In the early hours of March 16 Sunil Tripathi left the apartment he shared with other students on Angell St in the Rhode Island city of Providence and walked into the darkness.
A CCTV camera caught him on a zebra crossing, hands pushed inside the pockets of his ski jacket, and then he was gone.
Aware the 22-year-old student had been suffering from depression, his family quickly raised an alarm, getting in touch with the police, student organisations and even the FBI. They organised searches, appealed for help on social media and uploaded a cheery, home-made video on to YouTube urging "Sunny" to come home.
Last night the Boston Globe reported that police in Providence had pulled a man's body from the Providence River. Police Lieutenant Joseph Donnelly said that "it's very, very possible" that the body could be Tripathi's, but also said authorities would not know for sure until the medical examiner's office in Providence identifies the body today.
Last week, a lot of people thought they had seen Tripathi. Indeed, some people were so convinced he looked like one of two men identified by police as suspects in the Boston bombing that even before officials had named the two suspects, countless numbers of people were claiming the young man was the subject of a massive, unprecedented manhunt.
Then, just as quickly, when police revealed the men they were hunting were the Chechen-born brothers Tamerlan and Dzhokhar Tsarnaev, the matter of the young man of Indian background was hastily dropped. And yet Sunil Tripathi is still missing.
"The search is still on and we are trying our best to make it strong," Tripathi's sister Sangeeta told the Independent this week. "After the events of last [week], we are launching our message back to the community and trying to channel the general public ... The short of it is, we are still at it."
The story surrounding the false identification of Sunil Tripathi is a cautionary reminder of how the pervasive reach of social media can be used for both good and bad. It is an insight, too, of how prejudice might cloud judgment and reason.
Sunil Tripathi is 1.8m in height, weighs 59kg and has brown hair and brown eyes. When he disappeared last month he was wearing blue jeans, glasses, a black Eastern Mountain brand jacket and a woollen hat bearing the insignia of the Philadelphia Eagles American football team. Twenty minutes before leaving his apartment next to Brown University in Providence, he had been using his computer and when he walked out of the door he left behind his mobile phone, identification card and wallet.
Although he was born and raised in Radnor, Pennsylvania, the young man had been living in Providence since 2008 and he followed both his sister and brother, Ravi, in enrolling at the Ivy League college to study philosophy. He loves chess and music and his family say he is a talented saxophonist.
"Sunil is a capable and well-liked student," said Margaret Klawunn, vice-president of student services at Brown, which has been helping in the search for Tripathi and distributing flyers. "There is a lot of support from the Brown University family."
Early last year, Tripathi received permission to suspend his studies after suffering from bouts of depression and his family said they were in regular contact with him. When police searched his student digs, they found a note - "brief and vague" - that added to the family's worries. And yet his family say people who spoke to him the day before he went missing said there was nothing unusual about the way he was behaving.
As part of the effort to reach out to him directly, his family members created a bouncy, two-minute video.
In the video, his sister displays a Zanzibar FC soccer shirt she had bought for him, an aunt recalls a meal in which they shared spinach calzone, a friend remembers a trip they took to Florida's Hammock Beach, while his mother, Judy, says: "One of the things that I remember, that I would like to do with you again, is to lie with you on your pillow mountain."
Towards the end of the video message, Tripathi's father, Akhil, originally from the Indian state of Uttar Pradesh and who runs a software company, says simply: "Come back, son. Call us. Love you - Dad."
Precisely how Sunil Tripathi went from being the subject of a missing persons search by a loving family to someone supposedly wanted by thousands of police and SWAT team officers remains unclear.
But it appears that speculation started on the social news site Reddit. Several of those in the US who claimed on the forum last Friday that he was the man wanted by police said his name had come up in conversations between officers on the police scanner.
One woman claimed she had gone to Radnor high school with Tripathi and that images provided by police "looked like him" while Kevin Michael, a cameraman with a Hartford affiliate of the CBS television network, said on Twitter: "BPD scanner has identified the names: Suspect 1: Mike Mulugeta Suspect 2: Sunil Tripathi."
With the story taking hold like wildfire, a number of people then went on to celebrate how social media had apparently found the suspect in the "white hat". It was, said some, a victory for new media over the old school. All chose to ignore the fact that police had not named Tripathi as a suspect. They also ignored the fact that he looked very little like the man being hunted by officers.
A forensic account of events by TheAtlantic.com website shows that not only had the internet sleuths failed to identify the suspect, they had also not bothered to check the source of the claim. An examination of the Boston police department's scanner for that evening reveals that Tripathi's name is not even mentioned by officers.
"By this time, there was a full-on frenzy as thousand upon thousands of tweets poured out, many celebrating new media's victory in trouncing old media," said the Atlantic. "It was all so shockingly new and the pitch was so high and it was so late at night on one of the craziest days in memory."
The family of Sunil Tripathi became aware of the sinister twist to the Boston tragedy when they noticed a rapid increase in visits to the Facebook page and when people began posting messages. They hurriedly took the site down but on other social media forums they monitored how their beloved Sunil was being accused of involvement in the most serious terror attack in the US since the events of 9/11.
They felt utterly helpless. It was not until NBC reporter Pete Williams said on Twitter that Sunil Tripathi was not the man wanted by police that the mayhem started to ease.
As for their experience with social media, Tripathi's sister said she hoped the lesson people would learn from this would be to treat each other "with care and delicacy".
Online witch-hunt for wrong suspect
1. On Friday, three days after the Boston Marathon bombings, a person who claims to have gone to high school with 22-year-old Sunil Tripathi, an undergraduate student at Brown University who has been missing more than a month, posts a message on popular social news website Reddit saying she thinks she recognises him from grainy surveillance photos of the finish line.
2. A leading theory on Reddit's "FirstBostonBombers" thread, which was set up as a crowd-sourced investigation, incorrectly identifies Sunil Tripathi as "the white hat suspect" and it begins to trend.
3. A Twitter user named Greg Hughes tweets: "Boston Police Department has identified the names." Sunil Tripathi is wrongly identified as "Suspect 2" from an audiotape of police scanner transmissions by social media commentators.
4. There is then a mass information cascade on Twitter and Reddit in which thousands of people name and re-tweet Sunil Tripathi as "Suspect 2".
