Adriana was last seen in Rowland Heights, California just before noon on May 7, 1996. She called her mother at work and said she was going to rest at their apartment on Greencastle Avenue before attending her evening class. Her older brother later heard the front door slam and discovered his sister was missing and she had left a half-eaten sandwich and her purse, money, backpack and pager. She has never been heard from again. Adriana may dye her hair blonde. She has a mole on her left hand and a light-colored birthmark on her left leg.
