Now to an abc news exclusive. The family of an american husband, father, and grandfather is speaking out for the first time. They saw new video of their father on it. His new plea, fearing he's been forgotten. And a direct appeal to the president for help. This morning, this video is all a maryland family has as they prepare to usher in a new year without a husband, without a grandfather. The first proof in more than a year that warren weinstein is alive. He was working in pakistan when more than two years ago, gunmen storm his apartment and took him captive. It's believed he's being held by aman al zawahiri. He looked into the camera and said -- it teems that I have been totally abandoned and forgotten. I wanted to die right there on the spot. He has no idea how hard we have tried to get him back. But there's nothing to do to get him back because they don't tell you what they want.

Reporter: Her son, just a toddler, had figured out how to skype with grand qun pa before he went missing. We were sitting at the computer and he figured out how to skype grandpa. What would you say to him if you could? Just tell him how much I miss him. Sorry. I would just tell him that i love him. That I think about him every day. He ends the video with a plea to all of you. I think about each and every one of you every moment of every day. I think about each and every one of them every moment of every day. It's just about the same way here. Every moment of every day. We're thinking about that wife, those two daughters, their brar bravery. The state department saying they're working to authenticate this video. Our thoughts and prayers with all of them. We have new detail overnight about the australian ice-breaker
