AURORA, Colo. - Authorities in Aurora have released photos of the suspects sought in connection to a failed pipe bomb found at Mrachek Middle School on Monday.
The burned but unexploded device was found outside the school in Aurora, in an alcove between two brick buildings at 8:40 a.m., according to Capt. Wendy Lippman with the Aurora Fire Department. They believe the device was placed there over the weekend.
Students were evacuated and classes were canceled at the school, which is located at 1955 S. Telluride St.
Investigators said the device did not detonate, but did ignite momentarily.
"They thought they had the right pieces and parts in combination, but they were unsuccessful in making it explode," Lippman said. "They tried to start it on fire to detonate it and all they did was light it on fire and it burned itself out."
Security video at the school showed the three male suspects outside the school on Saturday around 6:30 p.m. Investigators said they would like to speak with them about the incident.
"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.
The new school year started last Tuesday.
