FRESNO, Calif. --It's a story of hope despite long odds. Family members and friends of Sammy Mercado are not giving up. They are posting and passing out flyers with pictures of the missing teen. They are hoping somebody knows what happened to the 16 year old and where he is. His Aunt, Sylvia Garza is leading the effort. "We're going to find him. We have high hopes. We don't want to give up."
