Melissa Kay LeSueur, 35, of Burleson, Texas, was found shot multiple times behind Seagoville High School in Dallas on June 11, 2007. She had been picking wildflowers that day. Melissa volunteered at the Dallas SPCA and was remembered for her kindness and love of animals, but had also struggled with a crystal meth addiction and associated with people who used and sold drugs.

Investigators treated the killing as a homicide but the case went cold after interviews with several persons of interest failed to produce charges. Detectives cite a lack of cooperation from people in Melissa’s social circle as a major obstacle, and her parents have expressed ongoing frustration and fear that the killer may never be identified.

Anyone who knew Melissa, her movements that day, or the people she associated with around June 11, 2007, is asked to contact investigators with information that could finally bring justice.
