It's been three months since three Americans – Shane Bauer, Sarah Shourd, and Josh Fattal – were arrested in Iran. They reportedly crossed an unmarked border while hiking in Northern Iraq and are being held in Tehran where government officials say they now face espionage charges.
The families say it was an innocent mistake and in his first television interview, Shon Meckfessel – the "fourth" hiker, who was not arrested – told CNN's Kiran Chetry what they were all doing there in the first place.
