Adriana Lisette Rojas was 17 and a senior at Rowland High School when she was last seen in Rowland Heights, California, shortly before noon on May 7, 1996. That morning she phoned her mother to say she would rest at the family apartment on Greencastle Avenue before an evening class. Her older brother later heard the front door slam and found Adriana gone; she left behind a half-eaten sandwich, her purse, money, backpack, and pager.

Adriana is described as Hispanic, brown hair and brown eyes, 5 feet 7 inches tall and 125 pounds, with a mole on her left hand and a light-colored birthmark on her left leg. She may have dyed her hair blonde and was believed to be wearing a pink top and white shorts. She had a history of running away, but previous absences involved taking many belongings; this time she took nothing. In the months before she vanished she reportedly acted strangely, grew distant from siblings and did not order a cap and gown for graduation.

Her mother believes Adriana ran away, while detectives say there is enough evidence to suspect foul play. The Los Angeles County Sheriff’s Office is investigating. Does anyone who lived in Rowland Heights in 1996 or knew Adriana have information to share?
