A threat made April 17 at Lehman High School caused an attendance rate just below 56 percent on April 20, Hays CISD spokesman Tim Savoy said. Hays CISD administration and police are now monitoring a threat made April 20 at Hays High School, the only other high school in the district. "We have had what appears to be a copycat threat at Hays High School this afternoon," Savoy said. A threat scrawled on a bathroom wall was discovered April 17 at Lehman High School. The author said in the note that he or she planned to bring a gun to school on April 20. The district in turn bolstered law enforcement presence on campus. Further, controlled and limited entry-points were made at the school for morning drop-off. School administrators and staff also checked students' backpacks, purses and other bags as they entered the school. Savoy said the investigation into the April 17 threat remains ongoing. He said law enforcement is zeroing in on a suspect and urged people with information on the case to call Hays County Crime Stoppers at 1-800-324-8477. "We have confidence the person will be identified and prosecuted as necessary," Principal Michelle Chae wrote in an April 17 letter. Savoy said 989 out of 2,235 students at Lehman High School were absent April 20, accounting for a 55.82 percent attendance rate. Attendance at Hays High School that day was normal, he said. Student absences will not be excused, but Savoy said the district will not use it against them to take them to truancy court. Also, students will be allowed to make up work without penalty, he said. The threat discovered in the afternoon on April 20 at Hays High School was also written on a bathroom wall. "We believe it was written this afternoon and was likely a copycat note because of the attention the threat at Lehman High School has received," Principal David Pierce said. "Our response to any and all threats is based on the type of threat received, what information the threat contains, and other factors. As principal, I want you to know that the safety and security of our students is my first priority. At this time there is no danger to any students or staff at Hays High School." In response the district is deploying additional law enforcement officers, who will be providing increased vigilance throughout the week, Pierce said. The district and law enforcement have opened investigations into the second case.
