Sunil Tripathi: Missing Ivy League Student Seen in New Surveillance Video
New surveillance video footage of a missing Brown University student on the morning of his disappearance may provide authorities with new clues to help locate him.
New images from a surveillance camera show 22-year-old Sunil Tripathi, of Radnor, Pa., moments after leaving his apartment at 1:33 a.m. on March 16, just 20 minutes after he last used his computer. Police said he left his wallet and phone behind.
"Typically, two reasons people don't take the normal things they take with them is because they're stepping outside to talk to somebody, they're going half a block away, or they're not coming back," ABC News consultant and former FBI agent Brad Garrett told "Good Morning America."
"His state of mind in those last interactions on the computer, in the last few hours that people knew where he was is important to assess," Garrett said.
