Nigerian officials believe the nearly 300 schoolgirls kidnapped by the Islamist extremist group Boko Haram have been split up and sent out of the country.
Hostage negotiators will be among the team of experts the U.S. is sending to Nigeria to help find them.
Clint Van Zandt is the FBI's former chief hostage negotiator and he tells Here & Now's Robin Young that the U.S. negotiators must first locate a Boko Haram member with authority to broker a deal.
Van Zandt says then they will advise on any ransom demands and most likely negotiate through a third party, like a family or company.
