Episode 416: Lisa Renee Triggs + Diana Lynn Houle

Lisa Renee Triggs was a 15-year-old girl from Dale City, Virginia, who was last seen on May 21 outside the Giant food store at Center Plaza. After a haircut with her mother, she asked to walk home alone so she could meet her boyfriend but that evening, she never made it back. Three days later, on May 24, her body was found in the woods behind the Dale City Recreation Center. An autopsy showed she died from blunt force trauma. Police had a main suspect but not enough evidence to make an arrest.

Three years later on August 14, 1989, Diana Lynn Houle’s decomposed body was discovered inside her apartment in Dale City, Va. An autopsy revealed blunt force trauma as her cause of death as well. Are these cases connected? Could it be just a coincidence they had similar details in their cases? Either way, Lisa and Diana’s cases remain unsolved and they need JUSTICE.

If you have any information about either case please contact the Prince William Co Police Department at (703) 792-5123 or send an email to policedept@pwcgov.org.
