THE body of the Brown University student who was wrongly identified as a Boston Marathon bomber has been found, news.com.au has reported.

According to the website, the Rhode Island medical examiner’s office says a body found pulled from a river in Providence is that of a Brown University student missing since last month.

Sunil Tripathi was one of the people who was wrongly identified as a potential Boston bomber, after crowdsourcing groups on Reddit posted his name as someone who resembled the suspect in a white baseball cap in FBI photos of the suspect. That man in the baseball cap was in fact Dzhokhar Tsarnaev, the suspect currently in police custody in hospital in Boston.

Health Department spokeswoman Dara Chadwick says the body of 22-year-old Tripathi was identified through a forensic dental exam. The cause of death has not been determined.

Tripathi’s family says in a statement they feel “indescribable grief” but are grateful for the outpouring of support.

Tripathi’s body was found on Tuesday by members of the Brown crew team in waters off India Point Park. Relatives of Tripathi, who’s from Bryn Mawr, Pennsylvania, had been searching for him with help from the FBI and Brown students since mid-March.

He had been on leave from the Ivy League school and was living with classmates in Providence.

Reddit general manager Erik Martin this week apologised in a blog post for the "dangerous speculation" that "spiraled into very negative consequences for innocent parties", and apologised publicly to Tripathi's family "for all the pain they had to endure."
