Hopewell Area School District in Beaver County was one of the school districts targeted in the active shooter hoax Wednesday.Police responded to Hopewell Senior High School around 10:20 a.m. after officials said the Aliquippa Police Department received a call that there was an active shooter inside of the building with six victims. The district went into lockdown.Pittsburgh’s Action News 4 talked with Michael Cox, a 7th grader at Hopewell Memorial Junior High School.“Basically, all they said was we are in lockdown. There is an intruder. This is not a drill ... I helped my teacher go put the fridge against the door, and then, I got under a desk,” Michael Cox said.Hopewell Township police Chief Donald Sedlacek said it took less than three minutes for his department to respond to the high school. Police agencies county-wide searched the building before students were evacuated.“I want to say it probably took us about an hour and 45 minutes to completely clear every open space, every bathroom, every outbuilding,” Sedlacek said.Catherine Noel, a retired teacher, watched the entire scene unfold.“To watch the kids come from the building, and as they came out, they are walking with their hands up in the air, and that has to be really scary,” Noel said.Once the scene was clear, students at both the junior high school and high school were escorted to their buses at a nearby shopping center. Cox's mother was reunited with her son outside of the school. “Everybody just came up here and stood around and waited…you just want to know that they are safe,” Brenda Cox said.Police said it just so happened that they recently did an active shooter drill at the high school.“All the neighboring departments, state police, local surrounding us had been in the building before, so we were well set to do a search of the building, and everybody kind of knew what to do, which we were lucky for that,” Sedlacek said.Beaver County District Attorney David Lozier said he believes the call came from out of state but had a message for everyone.“We will prosecute anyone that we find. We have prosecuted several juveniles in the past who made false claims. We will be aggressive on that,” Lozier said.Lozier added mental health professionals will be available for families and students for the rest of the week.“I think, unfortunately, we are doing everything we can. Most school districts and police departments are going above and beyond to try to protect their students, staff and public. The sad part of that, the other side of that is it’s hard to control evil people that have bad intentions and don’t think about the emotional distress that had on the students,” Sedlacek said.There were no reports of injuries. No active shooter was found at any location.The school district would operate on a two-hour delay on Thursday, superintendent Jeff Beltz said in a letter to parents. Additional police and counsellors would also be available throughout the district that day.
