Program note: Watch Anderson's interview tonight at 10p ETWhen I greeted Eric Volz and his family in the lobby of our CNN offices, it was hard for me to believe it was really Eric. I have been following his story and spending time with his family for 9 months, even traveling to Nicaragua where he was in prison, to talk to witnesses and try to get to the bottom of the murder for which he was convicted.

He was released last month after his conviction was overturned, and he came to New York for an interview with Anderson Cooper, which airs tonight on 360.
I have spent so much time thinking about Eric and his case, looking at photos of him and reading case information, that it was almost eerie for him to be standing in front of me, walking and

talking, alive and free.
He was warm and friendly, even joking about how certain things -- like using a computer-- instantly came back to him after his year in jail. Other things are still jarring-- like the cold winter weather here. He talked with Anderson about the daily struggle in prison to stay alive, grieving for his ex-girlfriend (pictured here) while being charged with her murder, and why he still doesn't feel like a free man.

The ordeal that Eric has been through would be terrifying for anyone, but he seems to have emerged still vigorous, and determined to clear his name.
