AURORA, Colo. - School was back in session Tuesday at Mrachek Middle School, one day after an unexploded pipe bomb was found outside the school in Aurora.
The device was found in an alcove between two brick buildings at 8:40 a.m., according to Capt. Wendy Lippman with the Aurora Fire Department.
Lippman said it appeared that the suspects attempted to detonate the bomb, but it did not explode.
Security video at the school showed the suspects outside the school on Saturday around 6:30 p.m.
"They have very good video of the suspects," Lippman said. "The school is working with our fire investigators on identification, but as far as images go, they are very clear."
Lippman said after the school was evacuated, the Arapahoe County bomb squad, along with a Denver Police bomb-detecting dog, searched the school for secondary devices.
The school was cleared, Lippman said.
Aurora Schools put a statement on Mrachek's website at 7 p.m. Monday:
This morning, we received a report of a suspicious device outside of Mrachek Middle School. As a precaution, we evacuated students to Rangeview High School and dismissed students at 12:30 p.m. We also canceled after-school activities today at Mrachek.
Student safety is a top priority in Aurora Public Schools, and we are cooperating fully with the police and fire departments, including the officers who are investigating the matter.
The Aurora Police Department and the Aurora Fire Department have informed us that the Mrachek school site has been cleared, and it is safe for students to return to school tomorrow, Tuesday, August 12. Mrachek will hold classes as normal at 8:30 a.m.
We sent an automated phone message to Mrachek parents to inform them that classes will resume at their normal start time tomorrow.
Because the incident may be upsetting for students and families, APS will have counselors available at school throughout the week.
As a precaution, we will also have extra security patrols in the area for the rest of the week.
Ensuring the safety of our students and staff is a top priority in Aurora Public Schools, and we appreciate the support of our families and community at this time.
The new school year started last Tuesday.
