Sunil Tripathi: missing student wrongly identified as Boston Marathon bombing suspect
Many hours later, the Boston police said both the marathon blast suspects, one dead, the other on the run, had both been identified as men from Chechnya.
Apologies followed. And the demand for apologies. "Sunil "Sunny" Tripathi, 22, is still missing... I send my deepest regrets for falsely identifying him as a suspect," said a Twitter user, who had earlier tweeted repeatedly about Mr Tripathi as a suspect.
