Details of Disappearance
Adriana was last seen at her residence in the 20 block of north Charles Street in Ephrata, Pennsylvania on November 28, 1988. Her mother saw her at 6:15 a.m.; they spent some time together in the kitchen before her mother went to work and Adriana went back to bed. Our Lady of Perpetual Help Catholic High School, where she was a freshman, was closed that day.
Adriana's stepfather, who had left earlier than her mother, arrived home from work that afternoon and was puzzled when he saw the curtains in the living room were still drawn; Adriana normally opened them as soon as she got up. His stepdaughter wasn't home and he assumed she was just out on an errand. She never arrived home, however. After Adriana's mother came home from work and she still wasn't there, her parents became concerned. They reported her disappearance to the police at 9:33 p.m.
There was nothing in the apartment to indicate anything was wrong, and little was missing. Adriana had left her purse behind, and books from her backpack were on the floor of the bedroom, but her backpack itself was gone, as was a change of clothes. Her friends stated she hadn't seemed troubled at the time of her disappearance and hadn't indicated any plans to run away. She left behind money in her bank account.
Authorities initially believed Adriana may have left of her own accord, possibly with an older man she knew. However, within the weeks they stated they thought she had been murdered. They have a person of interest in her disappearance, a man who no longer lives in the area and has not been publicly identified. Her case remains unsolved.
