24-year-old Jennifer Kesse vanished with out a trace on January 24th, 2006.

Detectives have searched tirelessly, but found virtually nothing.

"Honestly, at this point, I think my daughter was trafficked," says father Drew Kesse.

Living with that dark belief, Kesse has educated himself on the black market that sends young American girls to the far corners of the earth.

"It's a $32 billion a year business," he says.

Eastern Europe, Japan and Korea are the most likely destinations for young Americans kidnapped into the slave trade, according to Kesse.

"A large majority are people who want an American woman for themselves," Kesse says.

102,000 people are missing on any given day in the United States. Kesse believes it's naive to think that some not over seas being used as sex slaves.

But instead of wallowing in the pain of not knowing what happened to his daughter, Drew and his wife Joyce have been advocates for missing persons.

Drew Kesse is president of the Florida Missing Children's Day Foundation. He will speak Saturday at a fundraiser that's been organized by Stop Child Trafficking Now.

Kesse says he and his wife have also reached out to others whose loved ones are missing, including the family of Tracy Ocasio, an Ocoee woman who went missing in May.

"I've had many conversations with Joe(Tracy's father)," Kesse said. "We helped set some searches with some people that we had used in the past."

Needless to say, it's an unfortunate way to make new friends.
