Lisa Haenel, 14, left home in Glen Burnie, Maryland on the morning of January 15, 1993 to walk her usual route toward Old Mill High School and never arrived. Her body was found the next morning in a ravine behind the school; she had been stabbed and strangled. Investigators collected evidence at the scene, including a cigarette found near her body.

Years later that cigarette produced DNA that linked her killing to other Anne Arundel County murders and to a man already serving a life sentence for a separate 1994 homicide. In July 2004 Alexander W. Watson Jr. was charged with first-degree murder in Haenel’s death and two other cold cases; in August 2007 he pleaded guilty to all three and received an additional life sentence without parole.

Does anyone remember seeing Lisa that morning or have information about the area behind Old Mill High School in January 1993?
