Just days after the start of summer break, the Dallas School District is working to dispel a fabricated story about a mass shooting being told by a former student."It's my 26th year in Dallas, and I could tell you that, thankfully, we've never had an event like that in our school district, and obviously, you all know about it as well, so it's very troubling and disheartening that was a story that was being promulgated," said Dr. Thomas Duffy, Dallas School District Superintendent.The story about the shooting first surfaced in February at a gun control rally in Kentucky.Former Dallas student Calvin Polachek spoke about the incident that he claimed took the lives of more than 10 students, including his best friend and his brother. Polachek said, "A week later, I had to go back to school, and that was the worst part. You had to walk past that spot where I saw my best friend. Right, and pretend it was all normal. It was not normal, folks. That's been 8 years, and I've been talking about this every single day since then for 8 years. 8 years of talking about this, and there's nothing that's changed."Now, months later, Superintendent Duffy says the community is outraged that a made-up story such as this was so easily told."It was uh extremely disappointing that a media outlet would put something out uh like this that that hadn't been vetted out."Polachek is a recent grad of Dallas High School and, according to the University of Louisville, is there as a student.Numerous sources also told WTAE's sister station Newswatch 16 that Polachek was involved in student government and athletics during his time at Dallas. A former classmate called Newswatch 16 to say the story he's telling now is a lie."He had said that he went to Dallas High School, and in 2017, there was a shooting, and he lost his best friend and his brother, and he had to deal with that every day going through school. That never happened. That never happened. We never had a school shooting."Superintendent Duffy says he's not surprised by the community's response to the misinformation."Difficult situation. It was affirming in the fact that we have a great school district community really circle the wagons when this information came out, and while I wasn't surprised, it was an opportunity to affirm the great stakeholders that make up the school district."Newswatch 16 did reach out to Moms Demand Action, the organization that held the rally in Kentucky where Polachek told this false story.Their statement reads in part: "Calvin Polachek is not an active volunteer with Moms Demand Action or Students Demand Action, and we are deeply disappointed that someone would exploit the tragic, lived experience of many to use our platform to share a story that was not true."Newswatch 16 did reach out to Calvin Polachek for comment. He did not respond.
