For two months, Hamill has been exchanging email with a girl he calls Adona, who is also 16 but who is an Albanian Muslim trapped in Kosovo's troubles.
"She's caught in the middle of it, has no stake in it and has no control of it," Hamill told CBS News Correspondent John Blackstone.
He and other teen-agers working at Youth Radio in Berkeley, California, have given Adona a voice - reading her email from Kosovo on National Public Radio.
"I really don't want to end up raped, like with no parts of body, like the massacred ones," Adona wrote. "I wish nobody in the world, in the whole universe, would have to go through what we are."
Hamill hasn't revealed Adona's real name. He fears putting a teen-ager much like him in even more danger in a war-torn region of the world that she describes so vividly in her email.
"I'll tell you more about my life and me," she wrote. "I love having fun and doing crazy things. I used to hang out with my friends until 11:00 in the evening. We were never safe in the street, but now we're not safe in our homes."
Hamill says the electronic correspondence has given him a new look on things. "I pick up the paper and I look at the Kosovo headlines in particular, because they affect her," he said.
As the situation in Kosovo grows more tense, Hamill worries whenever a day or two goes by without an email from Adona.
"We have also brought warm clothes in case we have to flee our homes and go to the mountains or elsewhere," she wrote in her last email, which Hamill put on the radio Monday.
"We were in tears in the studio," he said. "The letter we got Monday was - the feeling we got - is it could quite possibly be the last one. She would have to leave at any moment, that her bags were packed. Her neighbors were fleeing. There were people being shot 100 meters away from her house."
In closing her latest message, Adona writes: "My brain, my whole life is just affected by reality. In just one picture of a dead, head-cut body or of a 3-year-old child massacred - which I certainly haven't imagined - you would be affected, too. If you were the ones to taste this bitter and cruel part of the world, you would understand me and my imagination. You would also understand the luckiness I feel for just being alive."
Now, with bombs falling on Kosovo, Hamill and his colleagues at Youth Radio can only wait, hoping they'll find good news in their email.
