 So there were five journalists who were killed. 1981 in San Francisco, 1982 in Houston, 1987 in Orange County, California, 1989 in Virginia, and 1990 in Virginia. All these crimes remain unsolved. 30-some years later, we don't know for sure who did these crimes and the victims have never gotten any kind of justice. My name is AC Thompson. I'm a reporter here at ProPublica and for the last two years I've been investigating the secret war that followed the end of the Vietnam War. In the U.S., from 1981 to 1990, there was an anti-communist desk ward that went around the country and killed people it didn't like. We know that they terrorized dozens of people. There were threats, fire bombings, there were communiques sent out saying, we're going to kill you. I got intrigued by the case because you see members of one ethnic group, Vietnamese-Americans, Vietnamese-American journalists who get killed one after another over a string of years and you wonder what is going on and why can't law enforcement get to the bottom of this. We've made a lot of progress. We've tracked down a lot of people, developed a lot of leads about who might be behind these crimes. We still want to get more information. We know that there's more victims out there. We may be able to bring some new answers to the families who survived these crimes. We'd like anyone that knows about any of these terror incidents from 1981 to 1990, any of these killings to come forth and share it with us. If you have information about other crimes that we don't know about yet, please contact us. If you were a victim of one of these crimes, please contact us.
