Every three seconds, someone in the United States becomes a victim of violence. This Sunday's Zombie Run For Your Life walk/run at Lake St. Clair Metro Park was organized to honor Theresa DeKeyzer and all victims of domestic abuse, bullying and post-traumatic stress disorder."We can't change what happened to Theresa," said event organizer, Victoria Hargan, a forensic behavioral health specialist with the Post Traumatic Stress Disorder Research Institute of Roseville.
